Route Legacy DNS to Ultralow instead of slower Anycast?

Hi,

Using NextDNS anycast IPs for legacy DNS, I'm routed to a server with higher latency than available Ultralow servers. Diagnostics confirm Ultralow is much faster for my location.

Is it possible to force/direct legacy DNS requests specifically to the faster Ultralow network, bypassing the default, slower Anycast server assignment?

I rely on legacy DNS for easy setup on various devices (IoT, older systems, etc.) where DoH/DoT is difficult.

Any way to achieve this preferred routing for legacy DNS?

Thanks for any help!
