Musescore Portable: using Fonts not installed on the system

[Augustinus-Altovadensis]

Hi everyone,
I've been using MuseScore 4.4.4 Portable, as I don't have the admin rights to my work computer.
I'd like to use an antique font that is not installed on the computer. A standard way is to copy the font files into the "PortableApps.com/Data/Fonts", where the PortableApps system loads them into memory and thus makes them available for most programs like LibreOffice, MS Office, Affinity Suite and many others.

However, not so in MuseScore.

My question: is there any way to make MuseScore Portable load those fonts, that are not installed in the system? Maybe a folder, where the program looks at start-up? And if not, would you consider adding this option in future releases?

Thanks a lot, have a nice day!
