Edit existing Network Routes

I always get frustrated when I try to edit my network routes because I can’t change the IP address or domain, nor can I add an IP address or domain to an existing network route.

I have to delete the route first before I can create it again to add another IP address or domain.

Is it possible to add a feature that allows you to add an IP address or domain to an existing network route?

Is there a specific reason you need routes and not just use “Networks”?
