Mainstage audio patches in Garageband

I would like to use (import) Mainstage audio patches in Garageband.

I know it is possible with software instruments, but I did not manage to do it with audio patches.

Since it is possible to save Mainstage strip settings to .caf files, it would be nice if I could import them to Garageband as track settings.

Any solution or workaround for this?

Thank you in advance.

Best,

Vincenzo
