Feature request: Make custom user fields available in Guide user object

The Helpcenter.user object offers limited data to Guide from Support - namely, things like basic profile info (name, email), user tags, and user orgs. It would be fantastic to have custom user fields also available, allowing teams to expand using features like Hiding Ticket Forms. 

It is not always feasible for Zendesk admins to split users into different orgs or apply user tags, especially when using SSO to provision users where the integration may be limited in what it can pass to Zendesk.
