Populate select_one with values from JSON

Question

We have several survey forms with individual fields that are populated with the results returned by custom javascript.  We now have a need to populate a select_one dropdown with choices returned from a javascript function.  Is this possible in the latest version of Survey123?

You'll probably want an external choice list, then. I haven't worked with them much, but perhaps you could export your layer's vales from the relevant column(s) to a CSV?

That is a slick way to filter a list of choices that already exist.  In my case, I would have to put 100's of thousands of choices into the spreadsheet to cover all the possibilities that are stored in the feature service.  What I am looking to do is dynamically define the choices without having to store any predefined values in the excel choice tab.
