QU-PAD: Some Assignable faders (eg. LR bass eq)

Some assignable faders in Qu-Pad would be great (in custom view) which lets you assign frequent used parameters…
Eg. In my case I would like to have a dedicated fader that controls the BASS EQ OF MAIN L/R output.

I use subs in my pa and sometimes need to make very quick changes in the bottom end where certain tracks are heavier than others…
A dedicated fader would be so much more convenient than going to the eq section, adjusting and coming back to main custom screen…

Aux fed subs?

A multiband compressor would help with this issue and certainly would be easier to implement than a single fader for an undefined group of frequencies.

I know I could use a separate MIX output for Subs but I like the convenience and internal Cross-overs in my JBLS (Prx715XLF and 710s) This way I’m only using one XLR cable for both Bottom/Top speakers
