Feature Request: Import nodes for outbound through subscription links and group them and update them regularly

Is your feature request related to a problem? Please describe. In my case, I need to use multiple nodes in an airport subscription connection as Outbound, and use the url-test function to automatically select the node. I noticed that outbound supports select and url-test, just like the general singbox client software.

Describe the solution you'd like

1. The most basic solution is to import multiple nodes through the airport subscription link and update the subscription information regularly.
2. A more complete solution is to be able to group all nodes of a subscription link as a urltest group. I can use the substore tool to split the airport subscription into multiple subscription links according to the rules and import them into s-ui.
3. The most complete solution is to be able to group subscription nodes by name, etc.

Additional context If you agree with a small part of it, please point it out.
