Spent $600 on two BE550's for my home. I have a router in my basement, and on the second story. These work great but lack advanced features needed to properly administer my home network.

my previous routers were ASUS. I had the option to bind clients to a specific node as clients did not always choose the best one. For instance, I have a chromecast in my living room and for whatever reason it loves the basement router. There's a strange issue where the signal isn't the best to the basement AP so I've always just bound the device to up upstairs router and had no issues. 
 

after setting up the new, shiny, immaculent WiFi-7 routers, I noticed this very simple feature is not present. The only option I have is to hard wire the chrome cast to a router to fix the issue. This is insane. Can a firmware update please fix this? Really not looking to hook my old ASUS routers back up but I can't even stream 4k media on my chromecast as the signal isn't good enough. I get 1gig up and down for speeds.
