I used to configure logistic belts in the former version with circuits because i use various dynamic assembler settings.
Currently i need to set all logistic controller logic manually via the chests.

I also don't see how i may have a chest separating two or more logistic belt realms.
In the former version i just disabled the routing functionality of the chest.

I have planned to add the configuration by circuit. I can also add the possibility to remove the routing for a specific chest (can act as a requester or a provider but does not propagate request)
