Feature request: Draw envelopes on multiple tracks

I love drawing envelopes directly on audio tracks, but its a bummer I can’t draw the envelope on two tracks simultaneously (I have two mono tracks instead of stereo and I want to adjust the two mono tracks as a pair)

Anyone know how to do this? I want to keep the tracks in mono so that I can quickly make an OMF. The DAW reading the OMF can’t receive interleaved stereo so I have to do it all in mono.
