I wish i could know if i've already tried profile xyz from the rig exchange and have already erased it as not suitable for me. Without this proposed feature, I may download and import it again, and spend my time auditioning it again for nothing.
And also if i've renamed the profile and it is still on the unit.
If all profiles ever created had unique hidden serial number, and a log was kept, and the unit had an option to "IMPORT ONLY PROFILES NEVER SEEN BEFORE" that would be cool!
