Location specific split-tunnel exclusion?

I have 2 geographically distinct networks in the ranges 192.168.8.0/22 and 192.168.12.0/24. I can use WARP on my home computer to connect to both but how can I enable devices in each of these networks to tunnel to each other? The setting for split-tunnel exclusion range seems to be at the account level. If I have 192.168.8.0/22 proxied then WARP works fine from a 192.168.12.0 device but the devices in 192.168.8.0/22 running WARP can no longer talk to each other.
