Biblatex: How to suppress same author of multiple citations?

Question

I need to use the features of biblatex's verbose citestyle but I don't want it to repeat the author's name in multiple citations by the same author (like the authortitle-comp option).

Currently, using the citestyle=verbose option, if I cite three works by "An Author" as:

\autocites{ANAuthor:1}{ANAuthor:2}{ANAuthor:3} 

the output is: "A. N. Author. 'First work' etc [full entry]; A. N. Author. 'Second work' etc [full entry]; A. N. Author. 'Third work' etc [full entry]."

But I need to have the output: "A. N. Author. 'First work' etc [full entry]; 'Second work' etc [full entry]; 'Third work' etc [full entry]."

Is there any way to do this in the verbose style? That is, suppress the author field in multiple citations for subsequent works by the same author?

Grateful for any assistance!

Update clarification

The only way to achieve this, I think, is to make a custom biblatex citestyle. Looking at the verbose.cbx the relevant command is the the printing of the bibhypertarget, as in the commands for full and short citations:

   \newbibmacro*{cite:full}{%  
        printtext[bibhypertarget]{%  
        \usedriver  
          {\DeclareNameAlias{sortname}{default}}  
          {\thefield{entrytype}}}%  
      \usebibmacro{shorthandintro}}

   \newbibmacro*{cite:short}{%  
      \printnames{labelname}%  
      \setunit*{\addcomma\space}%  
      \printtext[bibhyperlink]{%  
        \printfield[citetitle]{labeltitle}}}  

Does anyone know how to modify that to print the author field as blank when the same author appears previously in the same multicites command?

As @henrique said (in the comments), a combination of authortitle-comp and verbose should work:

\documentclass[english]{scrartcl}
\listfiles
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{article,
  author = {Arnold Author},
  title = {A journal article},
  journaltitle = {Some Journal},
  date = {2006},
  volume = {6},
  pages = {19-75}
}
@book{book,
  author = {Arnold Author},
  title = {Some Book},
  editor = {Edmund Editor},
  location = {London},
  date = {2000},
  options = {useeditor=false}
}
@collection{coll,
  editor = {Arnold Author},
  title = {An edited volume},
  location = {London},
  date = {2002}
}
\end{filecontents}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{babel,csquotes}

\usepackage[
  style=verbose,
]{biblatex}
\addbibresource{\jobname.bib}

\makeatletter
\newbibmacro*{cite:init}{%
  \ifnumless{\value{multicitecount}}{2}
    {\global\undef\cbx@lasthash}
    {\iffieldundef{prenote}
       {}
       {\global\undef\cbx@lasthash}}}

\newbibmacro*{cite:reinit}{%
  \global\undef\cbx@lasthash}

\renewbibmacro*{cite}{%
  \usebibmacro{cite:init}%
  \usebibmacro{cite:citepages}%
  \ifciteseen
    {\iffieldundef{shorthand}
       {\usebibmacro{cite:short}}
       {\usebibmacro{cite:shorthand}%
        \usebibmacro{cite:reinit}}}
    {\usebibmacro{cite:full}}}

\renewbibmacro*{cite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \usedriver
      {\iffieldequals{namehash}{\cbx@lasthash}
         {\ifboolexpr{
           test {\ifuseauthor}
           and not
           test {\ifnameundef{author}}}
          {\clearname{author}}
          {\ifboolexpr{
             test {\ifuseeditor}
             and not
             test {\ifnameundef{editor}}}
            {\clearname{editor}}
            {\ifboolexpr{
               test {\ifusetranslator}
               and not
               test {\ifnameundef{translator}}}
              {\clearname{translator}}
              {}}}}
         {}%
       \DeclareNameAlias{sortname}{default}}
      {\thefield{entrytype}}}%
  \usebibmacro{shorthandintro}%
  \savefield{namehash}{\cbx@lasthash}}

\renewbibmacro*{cite:short}{%
  \iffieldequals{namehash}{\cbx@lasthash}
     {}
     {\ifnameundef{labelname}
        {}
        {\printnames{labelname}%
         \setunit{\addcomma\space}}%
      \savefield{namehash}{\cbx@lasthash}}%
  \printtext[bibhyperlink]{%
    \printfield[citetitle]{labeltitle}}}
\makeatother

\begin{document}
\autocites{article}{book}{coll}
\autocites{article}{book}{coll}

\printbibliography
\end{document}

Note that there might be problems when author and editor occur in one work (the editor will be printed before the title), but you can circuit this by adding options = {useeditor=false} to the respective entry.

I'm not sure whether such an approach meets your requirements, but the siam.bst file uses a last.authors string to print a line instead of authors' names if they appear consecutively (see e.g. this example). I assume changing your bst file according to what is done in siam.bst (namely, the FUNCTION {format.authors} part), notwithstanding the additions you want to make, should solve your problem.
