Grade Criteria should be one of the options when assigning leaner to course task in advance

Hi team,

We have a client requirement to add a new advanced filter option for compensation grade criteria when adding learners.

When assigning learner to the course we navigate to "add learner » enrollment details » select learner» add"

When adding learner using the advanced option we require to add a new criteria to filter on compensation grade just like we can on business unit and departments.

Is it possible to add this new search option for Grade criteria, and if yes how can we do this?

for clarity, I've shared an edited image of how we roughly want it to look like.
