Automatic overview for a FAQ list [closed]

Question

In my answer to Enumerated description list you can see, that I've created a special list edtoclist and a list command edtocitem for an internal “table of contents” or in other words an overview, that I used for a FAQ-list in a bigger document. It works fine, but still needs a lot of manual work: The items of the second list (here: “enumdescript”) must be manually added to the “TOC” list (the “edtoclist”). Hence my question: Do you have an idea, how this could be more automated?

^{Oh, I know: The real answer would be “Yes.” or “No.”, but I’m interested in more elaborated answers. grin}

I must say, one big advantage of my manual approach is, that I could choose a different letterspacing for the same entry in the edtoclist and enumdescript. If that still would be possible, it would be great!

The code is:

\documentclass{article}

\usepackage[ngerman,english]{babel} % needed for "blindtext",
                                    % "english" is the active language

\usepackage [pangram,random]{blindtext}
\usepackage{lipsum,kantlipsum}

\usepackage{enumitem}

\usepackage[%
  colorlinks=true,%
  linkcolor=blue,%
]{hyperref}

% Custom counters:
\newcounter{enumdesci}
\newcounter{enumdescii}[enumdesci]
\newcounter{enumdesciii}[enumdescii]
% Redefinition:

\renewcommand*{\theenumdescii}{\theenumdesci.\arabic{enumdescii}}
\renewcommand*{\theenumdesciii}{\theenumdescii.\alph{enumdesciii}}
%
\newlist{enumdescript}{description}{3}
  \setlist[enumdescript,1]{before={\setcounter{enumdesci}{0}},style=nextline,leftmargin=0pt,%
    font=\phantomsection\normalfont\normalsize\bfseries\refstepcounter{enumdesci}\theenumdesci~}
  \setlist[enumdescript,2]{style=nextline,leftmargin=0.75em,labelindent=0.75em,%

  \setlist[enumdescript,3]{style=nextline,leftmargin=1.5em,labelindent=1.5em,%
    font=\phantomsection\normalfont\normalsize\bfseries\refstepcounter{enumdesciii}\theenumdesciii~}
