Can I enable Searching/Scrolling for the Assessment ID drop-down field??

Summary:

Can I enable Searching/Scrolling for the Assessment ID drop-down field housing the Assessments/Vacancies populated by Harver, our Screening vendor?

Recruiters setting up a req must chose the correct assessment/vacancy name from the drop down, located in the Screening section. This list contains ~100 items, and they're not in alphabetical order OR searchable, AND the drop-down visible space is very small. This makes for a VERY painful experience for recruiters and often results in them selecting the best one they see in the first 20 or so.

The assessment provider has indicated that this is not anything they control, including whether these assessments show up alphabetically or not.
