How to load serial numbers not in range while pick confirm for a movement request

Summary:

In pick confirm in inventory management, we need to select many specific serial numbers (Cannot use 'Enter single serial number' or 'Enter serial number range').
we have a option of 'select serial numbers' but cannot search and select 100's of serial number individually.

1. So is there Rest API available for loading serial number during the pick confirm.
2. You can also suggest alternate method to complete pick confirm if available.
