For reasons established in other threads subs off aux or even LR Sub is not recommendable, unless you use the aux or the Sub mix per channel only as a switch. If you change the level of the sub mix per channel to be different from the main mix, it will have negative impact on the phase coherence and the linearity of your overall system.

Of course making the lowcut switchable to higher orders of filtering will be a DSP problem. The higher the order/steepness, the higher the DSP usage.

Anyways, I’d like to see that feature too. Making it global, setting it for ALL channels from preference, would make it pretty useless again. You’ll need to decide PER CHANNEL what the right order/steepness is.
