Keyless Remote Programming

Does anyone know if this will work? I have a 2019 Yukon XL Denali and. 2018 Acadia Denali. The remotes are not identical. The Yukon remote has an extra button to open the rear glass. I have read the instructions in the manual about programming a new remote by placing both remotes in the slot in the center console and doing a few steps with the new remote. If I were to program my Yukon remote as a new remote for the Acadia, would my Yukon remote then start both vehicles or would it mess things up for the Yukon? It would be nice to have one remote for both cars.

My guess would be that the remote learns from the car (code) versus the car learning the remote code.  Otherwise, if you remote start one, the other would start also.  Not sure, but I would say the remote cannot work with both vehicles at the same time.
