Primavera Cloud REST API - GetAllXXXX Endpoint or wildcard for query parameter

I'm interacting with the REST API for Oracle Primavera Cloud. On several different calls, I've run into the issue where all of the available endpoints seem to require parameters that limit the scope of the results too much. Is there a way to make a call that is basically just "give me all the objects you have", so I can use the filters header to actually filter out the objects I don't want.

Some categories have calls where I can get all objects under a workspace (eg View all Projects by workspace /api/restapi/project/workspace/{workspaceId}). This works great for me. However, others have far more limited scopes available, like activities.
