Add fully adjustable 360 degree phase control in splitter

Fairly new Quad Cortex user here and I love this thing. For someone who plays regularly in stereo, but often needs to sum to mono, I have noticed that almost all amp captures have some sort of phasing which becomes noticeable when summing to mono or panning center with two amp captures. It would be incredible to have fully adjustable 360° phase control for the pan controls in the splitter settings. Even though there is a phase on and off, it is usually not very effective when simultaneously using 2 amp captures that are just slightly out of phase.
