Connecting google sheets/db to auto update the choices

I have been using an ODK form to track a very complex project activities, and most of the fields are related to another, in the sense, a farmer belonging to a certain district would only show up based on previous response, and similar dependencies.

But my data in terms of the choices keep changing on a very regular and fast pace, and I need the choices to be updated automatically rather than updating the xls form and reuploading it multiple times.
Is there a way to connect the choices to a google sheet which keeps getting updated? or some way to automate this process?

You'll want to use Entities. Read over the intro and try the tutorial.
