How to automatically embed cited PDF reports to a document?

Question

I have built a .bib file with some entries providing a file attribute.

I want this file to be automatically attached to the document (at the end, where the references are).

I'm already using biblatex to provide a direct http link to some references via the doi=true flag (references that I can't legally include as PDFs).

I'd like this:

As stated in my previous report, \cite{report1} ...

to be translated into that:

As stated in my previous report, [1] ...

[...]

References
[1] My interesting report, 2012 (click here)

Does anyone know about a package able to do that? I've asked google and CTAN without much success...

EDIT:

Here we are, an example of .bib file, let's call it refs.bib:

@Article{SomethingIDidntRead,
author = {Some Authors},
title = {The Early Typography of Printed Welsh (sounds great)},
journal = {The Library},
volume = {3},
pages = {217--231},
year = {1981},
doi = {10.1093/library/s6-III.3.217},
}
@unpublished{navigator,
author = {Some Authors},
title = {Navigator},
year = {2010},
url = {http://mirrors.ctan.org/macros/generic/navigator/navigator-doc.pdf},
file = {navigator-doc.pdf}
}

And the main.tex file:

\documentclass[
    fontsize=12pt,
]{scrartcl}
\usepackage{luatextra}
\usepackage{hyperref}
\usepackage[
    hyperref=true,
    backend=biber,
    style=numeric-comp,
    doi=true,
    url=true,
    block=none,
]{biblatex}
\addbibresource{refs.bib}

\begin{document}

This seems to be an interesting article\cite{SomethingIDidntRead}.
But I just took it at random for its \textsc{doi}.

This file is also interesting\cite{navigator} and I'd like it to be embedded.

\printbibliography
\end{document}

What I want is to know if there is a package that takes the file name I provide in the .bib file to automatically and embed it to get file:click here just as I get doi:XXXXXXX.

If no package provides that, we'll see what can be done.

Thanks for your attention.

Answer 1

First I found this: http://tex.stackexchange.com/a/65403/15283 But I don't have biber 1.0+ nor biblatex 2.0+... The given solution won't work on my TeXLive 2012 installation.

Then I found that the file field was indeed parsed but not used in the usual style formats, I read the doc and here we are:

\usepackage{attachfile2}
%Declare the "file" field format
\DeclareFieldFormat{file}{\bibstring{file}\addcolon\space \textattachfile[color={0 0 1}]{#1}{Click me!}}
\renewbibmacro{finentry}{\finentry\addspace\printfield{file}}

Easy was't it? :P

Thanks for your input.
