[Tex/LaTex] \nocite-like macro for \footfullcite in beamer

Question

Is there any macro similar to the behavior of \nocite?, in the sense of printing an entry of the bibliography, but for putting the citation verbatim in the footnote, similar to \footfullcite but without the footnote superscript somewhere in the slide, and that works on beamer.

I want to show some reference in the bottom of a slide, but I don't want to put a reference number in particular in the slide. Instead, I want the reference to be just in the bottom of the slide (as a footnote).

I went through the biblatex manual without luck. Any ideas or suggestions?

If by "reference number" you mean the footnote mark, you can define a variant of \footfullcite that suppresses the mark:

\newrobustcmd*{\footfullcitenomark}{%
  \AtNextCite{%
    \let\thefootnote\relax
    \let\mkbibfootnote\mkbibfootnotetext}%
  \footfullcite}

Here's an example demonstrating two variants - one that only suppresses the mark and another that prints the footnote without any indentation.

\documentclass{beamer}
\usepackage{biblatex}

\newrobustcmd*{\footfullcitenomark}{%
  \AtNextCite{%
    \let\thefootnote\relax
    \let\mkbibfootnote\mkbibfootnotetext}%
  \footfullcite}

% based on default footnote template from beamerinnerthemedefault.sty
\defbeamertemplate*{footnotetext}{default}{%
  %\parindent 1em\noindent%
  \raggedright
  %\hbox to 1.8em{\hfil\insertfootnotemark}%
  \insertfootnotetext\par}

\newrobustcmd*{\footfullcitenomarkleft}{%
  \AtNextCite{%
    \setbeamertemplate{footnote}{\usebeamertemplate{footnotetext}}%
    \let\mkbibfootnote\mkbibfootnotetext}%
  \footfullcite}

\addbibresource{biblatex-examples.bib}
\setbeamertemplate{navigation symbols}{}
