Dataset model documentation gets removed when data source is changed.

Hi everyone,

I have a Power BI Dataset that was connected to databricks via a spark connection.

Within the modelling view I have added documentation to the field descriptions, and I have also added folders to separate out the different fields into similar areas.

I recently updated the data source to use Azure databricks which should have the exact same data in it.

When I do this, all my field description and folders are removed.

This means that I must go and manually re add all of the dataset field descriptions and folders for each dataset when I update the source to use Azure databricks. 

Is there any way of preventing this from happening? Is there a nice JSON file that can be used to maintain model information like there is for themes?

I think this would be useful as developing with Power BI can be a pain when having to manually re add information to datasets when changing connections etc. 

Thanks
