Setting caps on certain resources in the resource pool

We are wanting to set caps or restrictions on certain resources in our resource pools so that they only have a specific number of hours allotted for the year to limit their engagement in Workfront. This use case is governed by certain contracts or seasonality of the workers. Does anyone else have a similar use case and how to support this need? Any inputs or feature enhancements in Workfront would be great to include this ask for putting a limit or cap on certain resources within the resource pool.
