Seems like this is restricted to a few Apple applications. Is there something more generic to run older software? There was a “Swiss Army Knife” application for handling media files (mainly audio and photos? I forget) called Media Rage, by Chaotic Software. The company seems to have gone out of business (the domain is now parked with ads). Since Media Rage was 32-bit, it wouldn’t work from macOS Catalina.
