Orbi - why can't we change channels on satellites?

I'm not sure using a different channel on satellite 1 would alleviate the issue. Seems like a workaround to me (for this problem) and the problem here really is the intel chip / linux combo somehow refusing to roam to satellite 1 despite crappy connection.

The *real* reason why I want different channels on the satellites and router is

1.) the routers / satellites are at the sides of the house (inside, of course), facing different neighbors. I can see roughly 2 to 3 neighbor networks from each side of the house (different ones). It's a rural area and the house has a rather large footprint. So naturally (since neighbors tend to select differing channels), each side of the house has a different "optimal" channels to be used there (I use from outdoors). I cannot find a channel that doesn't conflict with a neighbor network on at least one side of the house. I can't ask the neighbors to reduce tx power because they also have not small houses and use single APs, so the have to use a bit of power to cover they hosues / outdoor areas)

2.) internal interference: This is more of a feel-good thing for me since I don't have real data to back up this problem actually has impact, but obviously (as can be seen by my problem description) there are many points in the house where I can see 2 or even 3 of the satellites / router. It just seems more clean to me to use separate channels and I don't really care if my devices keep roaming around in those overlapping areas.
