Add a way to specify a parameter for multiple routes at once

[iTrooz]

Is your feature request related to a problem? Please describe.
I have a bunch of endpoints like this:

/user/{user_name}/posts/{post_id} [GET]
/user/{user_name}/posts/{post_id} [POST]
/user/{user_name}/posts/{post_id} [DELETE]
/user/{user_name}/posts/  [GET]

I'd like to define the {user_name} and {post_id} path params, but without duplicating them their definition (the description being the most problematic) for every endpoint

Describe the solution you'd like
A way to define the path params once when they are used in multiple endpoints. Maybe by defining "global params" by their name ?

Additional context
Apologies if the feature is already present, I could not find it in the README or already opened issues

I found some information in the documentation that might address your concern. You can find details on how to add multiple paths here: Add Multiple Paths.

Does this help resolve your issue?
