Multiple references with \footfullcite

Question

I use \footfullcite{} to include the complete reference in footnotes on the same page. I now have the problem that I want to cite multiple references. Either I would like them to be separated by a semicolon in the footnote so that

Check.\footfullcite{Book1, Book2}

would give the following output

Check.[1]

[1] A. Author, Alpha, 2001; B. Buthor, Bravo, 2002.

or, ideally, I want it to look like this

Check.[1-2]

[1] A. Author, Alpha, 2001.

[2] B. Buthor, Bravo, 2002.

Is this possible by using \footfullcite?

\documentclass[a4paper]{scrreprt}
\usepackage[backend=biber, style=chem-angew, safeinputenc]{biblatex}
\begin{filecontents}{\jobname.bib}
@misc{Book1,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
@misc{Book2,
author = {Buthor, B.},
year = {2002},
title = {Bravo},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
Check.\footfullcite{Book1}
Check.\footfullcite{Book1, Book2}
\end{document}

Answer 1

By adding

\renewcommand\multicitedelim{\addsemicolon\space}

to your preamble, a semicolons is placed between multiple items. Found this here.

Answer 2

For me, the above solution by @hnina didn't work. So as an instant solution, I did it in the following way-

\footfullcite{abc}$^{,\hspace{2pt}}$\footfullcite{xyz}
