Support for custom exit node

Using ControlD to bypass geo-restrictions is great, but many services seem to increase detection and blocking of IPs (especially none US ones). I happen to have OpenWRT devices at family members' homes in other countries that I could use for this purpose.

Currently, my workaround is to manually VPN into one of those devices first, then access the service. This works, but it isn't practical for devices that don't support VPN clients natively and I'd like to avoid routing everything through a VPN.

Would it be possible to configure ControlD DNS to route traffic through a custom WireGuard peer or proxy as an exit node? This way, traffic would appear to originate from a residential IP without requiring each device to connect to a VPN separately.

Access to this exit node would obviously need to be restricted to the owner account only. I'm not sure if this is possible in ControlD's architecture, but wanted to ask if it would it in case it's feasible.
