Mainstage Copies Audio Samples Upon Every Save

I'm on MainStage 3.2.3

I have a Concert that every time I save, it copies all the audio samples.

Its a rather large Concert and I'm a constant "better save this" guy.

the save takes about 30 seconds ... and when I'm in a show, without sound for 30 seconds just isn't cutting it.

Any way to avoid this?
