i'd like to suggest that when we transform a MONO audio track (to "freeze"/print the Inserts in audio), it should generate the new Track with the same PAN as the original one...
currently as I see it, if we have a mono track panned to L, then you Transform Audio Track, the new track gets in PANned to Center.
there are workarounds, for example transforming the track to Stereo before freezing it.... but anyway, I think it would be consistent for the algorithm to "copy" this PAN when it's transforming the mono track.
