Sharing presets between two users on same Mac

I am using Pianoteq as a Logic Pro plug-in for two users on the same Mac, user A and user B.

As user A, I installed Pianoteq, added an instrument package, downloaded and added the historical instruments, and saved a bunch of presets.

As user B, I saved one preset.

Unfortunately, user A can't see or load user B's preset and user B can't see or load the historical instruments or user A's presets. I tried creating aliases to to the opposite user's preset folder in /[username]/Library/Application Support/Modartt/Pianoteq/Presets without that resulting in the presets becoming cross-available.

Does anyone know a way to grant user B access to the historical instruments (I realize I can re-install these as user B but would prefer not to duplicate data) and to user A's presets (as read-only would be fine).
