You can currently copy a specific EQ band to another channels EQ band, but you cannot copy a band and replace a band on that same EQ.
Let’s say you’re using LF LM HM at 250 500 1k and HF is still available
You have a problem let’s say at 120, you can move your HF down, but you then need to remember that channels configuration.
Would be nice to just copy your HM to HF, LM to HM, and LF to LM, this would then free up LF.
In general you could copy/paste any band to any band, with the exception being the LF/HF set to shelf or cut mode, then the console does the (cannot copy shelf/cut) at the top of the screen.
