I've started using the OneMesh feature with my AX11000, an RE315 and RE605X.   It's working well.  My question is can I connect the extenders to different 5ghz bands on my AX11000 within Onemesh?   By default they connect to the lower 5ghz band which is leaving my high 5ghz band on the AX11000 fairly unused.    Ideally, I would like to connect one extender to the low band and one to high band to try and get some utilization on that upper band.
