Linking front foot well lights to ambient lights?

Has anyone attempted to link the front foot well lights to the ambient lights in the doors? On the Model 3, I noticed that the foot well lights are on at night. On the Model S, the foot wells are pitch black at night, and I thought it would be nice to have it linked to the ambient light setting. I know it could/should be controlled via software, but the likelihood of having that feature added is probably very low, So before I go and tear apart the door to figure out the wiring harness, I was wondering if anyone has figured this out already.

I have the upgraded extra bright LED foot well lights, I'll likely cut an extra hole in the liner and install the original lights as secondary ambient lights. I guess I could just add the secondary lights and have them wired to a switched 12V source, so they would be on anytime the car is on, but I thought it would be clever to link it to the ambient light toggle.
