Reviewing the workgroups database break down. I am not finding a way to pull out the metadata of which groups are assigned to which projects. Though I am not an expert on our workgroups data base and there might be some one else in the community who has ideas.
This would be an excellent addition to the Workgroups database though and I would suggest creating an Idea on the Tableau Ideas forum. Ideas
Ended up going to postgre data base and pull the information from there. Not pretty but it did work.
