Envelope Detail - multiple view?

I love the detail view of the Envelope, that visual feedback is just wonderful. Would it be possible to create a display function so that two envelope details could open simultaneously? Very frequently you may want to adjust both the VCA envelope and the VCF envelope at the same time. You could then have the top row of four center knobs assigned to the “upper” envelope, and the bottom row assigned to the “lower” envelope respectively. This would be très cool…!
