Request: SmartThings Dongle Thread Network editor

So I made a group for my hub v3 + station and they both now share a thread network which I added my Google, Apple, and Homeassistant border routers to.

But my dongle accepts other border routers without letting me move it to another network, I know your Hub Groups block it as a secondary hub but surely this should be possible right? The TV has enough processing power and internet connectivity + Bluetooth to enable matter & thread.

So can we have an option or route to let us configure the dongles thread settings and add it to other networks? It splitting off into its own openthread network has already made things messy for me :confused:

Would appreciate any advice in how to get this working, already used Nanoleaf to merge it with Homeassistant and Apple but that pulls those off my main hub group network
