Question on Multiple Golden Datasets with RLS

[RobiFitz2]

My company has multiple large servers pulling in a large sum of data for almost a hundred reports for our vendors. Currently each report has its own dataset pulling in some form of data that is similar to the next dataset however the query is fine turned towards that report and every report has RLS for each vendor.Everytime a new person is needed to be added to the vendor, we have  to go through each dataset and add them to RLS. My question is, is it possible to have 5 golden datasets(1 for each server), then connect them in the report and setup RLS on 1 of them to only display data related to that vendor? I thought about 1 golden dataset however It is an extremely large amount of data with fear of the queries timing out

If your golden dataset only contains the data required for RLS,  and all other datasets include that dataset in their data model in a controlling fashion then this will work.

Instead of adding individuals to RLS see if you can use distribution lists.

2 questions come to mind, by controlling fashion you mean like a star scheme with the dataset with RLS in the center of all datasets correct? Also any documentation you can provide on distribution lists would be great!
