Power Control for R8000

Please add the "Transmit Power Control" setting for the R8000. I want to reduce the power control like I can on my R6400 router but no option is available for the R8000. Reducing power transmission is key for home networking with Access Points, where you want your devices to automatically switch to most nearby router that has the same SSID. Without this option, your devices hold on to the further away router with a weak signal.
Thank you!
