biblatex-dw: Using back references in footnotes

Question

Problem

Using the biblatex package with the authortitle-dw style I'd like point from a footnote back to its first occurence -- where it has been cited as a whole due to the firstfull=true-option -- as shown in the following picture:

^{(of course not in red and not with another font :) )}

MWE

\documentclass{article}

\usepackage[
    style=authortitle-dw,
    backend=biber,
    autocite=footnote,
    firstfull=true,
    singletitle=true,
]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book {foo,
    author = {Foo, Francis},
    title = {All about Foo},
    year = {2011},
    location = {Footown},
}
@book {bar,
    author = {Bar, Bernie},
    title = {Barstory},
    year = {2000},
    location = {Barcity},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\textheight=150pt

\begin{document}

\autocite{bar}
\autocite{foo}
\autocite{bar}
\autocite{foo}

\end{document}

This produces the following output:

Expanding on Marco Daniel's comment: biblatex-dw features two styles: authortitle-dw (based on the standard authortitle style) and footnote-dw (based on authortitle-dw, and similar to the standard verbose-inote style). The main differences between authortitle and verbose styles are:

• For authortitle styles, one is supposed to look up the full bibliographic information in the (mandatory) bibliography. By default, these styles do not display full information in an entry's first citation. (authortitle-dw offers the firstfull option, which is set to false by default.)

• verbose styles, on the other hand, do without a bibliography (though one is often added for convenience). The full bibliographic information is displayed in an entry's first (footnote) citation (which may introduce a shorthand for this entry), and follow-up citations will either use the shorthand or include a pointer to the first citation.

Bottom line: If you'd like to "point from a footnote back to its first occurence", you are looking for a verbose style (here: footnote-dw).

\documentclass{article}

\usepackage[
    style=footnote-dw,
    backend=biber,
    autocite=footnote,
    singletitle=true,
]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book {foo,
    author = {Foo, Francis},
    title = {All about Foo},
    year = {2011},
    location = {Footown},
}
@book {bar,
    author = {Bar, Bernie},
    title = {Barstory},
    year = {2000},
    location = {Barcity},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\textheight=100pt

\begin{document}

\autocite{bar}
\autocite{foo}
\autocite{bar}
\autocite{foo}

\end{document}
