Thanks for sharing this, Poised Barracuda. Having a way to define and prepopulate the Data source(s) field when creating or updating users makes a lot of sense, especially if you are not using Autopilot or one of the built in integrations.

Right now, data sources are tied to where the user data is synced from, like the SDK or an integration, so they are not something you can manually set in Canny.

I have logged this as a feature request and we will let you know if we have an update.
