Ability to edit multiple files at once and automatic phase rotation

A possible plugin to try for phase rotation is https://x42-plugins.com/x42/x42-phaserotate

Voxengo also has a tool:  https://www.voxengo.com/product/pha979/

Airwindows also has one, but I don't favor plugins with sad UI's.  The plugins are quite good though, just annoying.  https://www.airwindows.com/phasenudge-vst/

Soundop is indeed a fabulous DAW.   And the developer is a superb, brilliant gentleman.  I'm very happy to be out of the Adobe ecosystem.
