Search Functionality when Mapping Requirements to Test Cases

When mapping a Requirement to a Test Case, is there a way to search on the mapping modal? We have many requirements and multiple teams, and filtering through the full requirement list, even divided by team, is very time consuming and increases our risk of grabbing the wrong one. If there was a way to search by the requirement name, Alt. ID, etc. this would make the process more accurate and less cumbersome. I've tried following the mapping from the requirement to test case, as well as the test case to requirement, but I don't see any search functionality either way. Am I missing something?
