Ability to deactivate tablet slots in map device with one click.

I have a set of 3 tablets that I wanna use on good maps and don't wanna use on bad ones.
And now I have to constantly move those in and out of map device if I don't wanna waste good juice on shitty maps.
It's terrible design.

Make a button or something in map device that activates and deactivates tablet slots, so I could easily turn them off while running bad maps (whitout the need to actually take tablets out).

Or even better, allow us to have two sets of tablets and swap between those via map device. So I could burn through bad tablets in bad maps, and use good tablets on good maps.

PS
Although I hope this whole tablet mess is a temporary solution and you'll come up with something better. I really hate it.

I concur
