What to do with an extra U7?

So I just realized I over ordered when I did my full Unifi setup and have an extra U7 Pro that I found in the garage. It’s new in box but way after the return window.

My deployment is stupidly dense … 3000 sqft house with 7 APs including two dedicated outside. Lots of Ethernet runs to rooms as well and what can be hardwired is.

So real question is what I should do with my extra u7. The only place I have subpar signal is in my driveway but my house has metal studs and the outdoor APs were the only way to get reliable signal outside. This js an indoor AP and my wife probably will not let me put any on the front of the house 😂
