Power BI Shared Data Sources (On-Prem)

OK, here's our situation.

We have multiple divisions in our company with a common data model.  (Division A and B for this example).

Here's what we want to do.  We know we can do this in deployed SSRS reports with data sources, but not sure about deployed Power BI reports to on-prem report server.

We want to deploy the same Power BI sheet to two report servers  (for Division A and B).   The deployed PBI report on report Server Division A will point to the database server for division A

The same deployed PBI report on report Server Division B will point to the database server for Division B.

On both deployed reports on the 2 different servers, a schedule will be set to refresh every 60 minutes or so.

Again, we only want to do this with one physical report (otherwise we run into hassles with version control).  

When we look at the data source on the deployed PBI report, it's disabled - doesn't seem like we can change it.

Any thoughts?

Thanks...
