Update Sub affects channels that weren't originally in the Sub

which video is this (preferably with a time, when this is mentioned)? Update will always only change stuff but not add things. to add you need to use Record.

Maybe i am confused but update update any manual data regardless of whether was in the Sub? I cannot recall it ever behaving differently. If you do not want manual data to update you have to use selective store.....
