You have the ability on normal Tables to import from .csv and export to .csv.
It would be deeply helpful to add that same functionality to the custom User Table fields.
I know you wouldn’t be able to append new records because that would require actually adding additional users, but it would be super helpful to have the ability to export that table, mass update those fields, and import it to overwrite/modify the custom table fields for only records that exists.
It would also be helpful to add a search field on the custom user field table. You have that search feature for the main User menu, but don’t have one after you click into the custom user table fields.
