Add Current Model (before data refresh) as PowerBI Desktop DataSource

Similar to excel.currentworkbook () in Excel/PowerQuery it would be extremely useful to have a CurrentModel () data source in PowerBI Desktop, that allows to get any table (or DAX query) from the existing model, note: the data *before refresh* , not the data from the new execution.

Among others this would allow for easy incremental loads and accumulating snapshot patterns like in the post below.

see here for a sample using Excel PowerQuery;

Incremental data loads in Microsoft Power Query for Excel by Hilmar Buchta

Currently it's already possible to connect using tcp/port but it's hacky, obviously not supported, and won't work in pbi service or without manual setup.

Even if an automatic load incremental appears in the future I think seeing the current model data would still be useful in a lot of ways.
