Dropdown list from static file (without background process)

Hi there,
I asked this before a couple of months ago, but I was wondering if maybe there was a new way to solve this:

I need to pass a list from a csv file to a Dropdown control in Apps, but without running a background process (we need to avoid the time delay of the process reading the list).
I’ve been trying with the new connectors (specifically the Onedrive), but I can’t seem to make it work.

Is there any news or ideas on this subject?

Have you thought about pushing your csv data to Data Service using an unattended robot? You could potentially do this on a schedule.

Hi Evan. Thanks for the reply.

Data Service is currently unavailable for me, so I was looking for alternatives. But in the meantime, I have escalated the issue to see if I can integrate Data Service to our Apps.
