rest – How do I assign methods if I have 100 endpoints in a RAML specification?

I'm trying to build a RAML API specification for the first time. The API should give users access to 100 resources (endpoints), so I'm not sure how to assign them methods. I suppose there has to be a more efficient way to do it than to list them all and assign methods individually.

Would it make sense to include a matrix in the base URL and access / interact with its elements through the query parameters?
