Is your feature request related to a problem? Please describe.
Some (or maybe many) proxy applications (Happ, v2rayTun) allow you to import the routing configuration from the link.
Describe the solution you'd like
I suggest implementing an editor for routing rules and making a separate endpoint for issuing them to users. For example, use this type of link https://panel-host.io/rules /{rule_id or short-name}. In the panel, create a separate section for the editor, which will allow you to reconfigure the rules, make them available by link, delete and change their prefix.
Documentation from happ and v2raytun:
https://docs.v2raytun.com/overview/supported-headers#routing
https://www.happ.su/main/dev-docs/routing
Additional context
I know that Happ reads certain headers (Routing) when updating a subscription, and if there is a link there, the application tries to receive the content and force routing.
It would be cool to make a subscription option that will take the standard routing rule (if set) and insert it into the header.
A screenshot confirming that v2raytun is able to work with such links
