MainStage: Connect Launchkey and Keylab on separate MIDI

Connecting Launchkey and Keylab to Mainstage on separate midi channels?

I'm using Analog V with Keylab 88 and Pigments with Novation Launchkey. I'm trying to get one preset from each controller to run together on MainStage. I've spent two nights with ChatGPT trying every configuration imaginable and now Chat is telling me it doesn't think it's possible.

Any thoughts?
