Bulk Modify Database from Bubble Client

I have an app that the end user “admin” needs to be able to submit a MODIFY CSV to bubble.

I understand that you can do this through the bubble admin panel, but I need it to be done through a client interface, like you can if you are adding new entries (using a workflow to upload a CSV). This way, a client (employer) can bulk modify its users (employees) each month as things change for existing employees.

Thanks and much appreciated.
