biblatex-ieee and supra note

Question

I know this is sort of short notice (I'd posted a similar cry for help at LaTeX Community), but I have a thesis due Monday and the one thing standing between me and being ready (layout-wise) is this: I'm using biblatex with a slightly tweaked biblatex-ieee style (maybe not ideal but my thesis director had very specific directions and that was the closest) which I call with:

\usepackage[bibstyle=ieee,citestyle=authoryear,backref=false,hyperref=false]{biblatex}

But the problem is I need to replace already referenced items with "supra note". For example, if Belloni is referred to in footnote (\footfullcite) 17 as:

17. R. Belloni, « The tragedy of Darfur and the limits of the ‘responsibility to protect’ », Ethnopolitics, vol. 5, no 4, nov. 2006, pp. 327–346.

I would like future references to the same author and article to look like (say in footnote 24, where I specify a page of the article):

24. R. Belloni, supra note 17, p. 336.

Any idea?

Thanks a lot in advance!

PS: It actually seems like the "citestyle" can be removed or modified without any change. I guess that is itself isn't normal...

Use citestyle=verbose-note plus the following modifications.

\documentclass{article}

\usepackage[bibstyle=ieee,citestyle=verbose-note,firstinits=true]{biblatex}

\DefineBibliographyStrings{english}{%
  seenote = {supra note},
}

% Print first name of authors in follow-up notes
\makeatletter
\renewbibmacro*{footcite:note}{%
  \ifnameundef{labelname}
    {\printfield{label}}
%     {\printnames{labelname}}% DELETED
    {\DeclareNameAlias{labelname}{default}% NEW
     \printnames{labelname}}% NEW
  \ifsingletitle
    {}
    {\setunit*{\nametitledelim}%
     \printfield[title]{labeltitle}}%
  \setunit*{\addcomma\space}%
  \printtext{%
    \bibstring{seenote}\addnbspace
    \ref{cbx@\csuse{cbx@f@\thefield{entrykey}}}%
    \iftoggle{cbx:pageref}
      {\ifsamepage{\the\value{instcount}}
                  {\csuse{cbx@f@\thefield{entrykey}}}
         {}
     {\addcomma\space\bibstring{page}\addnbspace
      \pageref{cbx@\csuse{cbx@f@\thefield{entrykey}}}}}
      {}}}
\makeatother

% AS A MEASURE OF LAST RESORT, assign the functions of \autocite to \footfullcite
%     (The correct way is to replace every instance of "\footfullcite"  in the text
%     with "\autocite")
\let\footfullcite\autocite

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@article{Bel06,
  author = {Belloni, Roberto},
  year = {2006},
  title = {The tragedy of Darfur and the limits of the `responsibility to protect'},
  journaltitle = {Ethnopolitics},
  volume = {5},
  number = {4},
  pages = {327--346},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

Some text \footfullcite{Bel06}.

Some text \footfullcite[336]{Bel06}.

\printbibliography

\end{document}

(The filecontents environment is only used to include some external files directly into the example, so that it compiles. It is not necessary for the solution.)

EDIT: After a lot of comments, here's the code to the OP's last-minute request:

\DeclareCiteCommand{\smartcite}[\iffootnote\relax\mkbibfootnote]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \iffootnote
     {\usebibmacro{footcite}}
     {\usebibmacro{cite}}}
  {\multicitedelim}
  {\usebibmacro{cite:postnote}}
