What I think would be really useful is a tool whereby we can setup an endpoint base URI and then it collects any subsequent requests. For instance:

example.com/my-base-path

This would catch requests and report on them for the following:

example.com/my-base-path
example.com/my-base-path/webhook
example.com/my-base-path/webhook/product/id

etc.

We could use this as a permanent tool during testing of our application then.
