Create Multiple Apps per Workspace

Recreating this idea, since the previous version seems to have been deleted.

One app per workspace is extremely limiting in large organizations, where many different subsets of reports need to be shared with different users. One example: I have a collection of reports in an app. All need to be shared with management, but only some should be visible to non management. Currently, I would have to create multiple workspaces with duplicate reports to accomplish this. Using datasets across multiple workspaces does NOT fill this use case. An alternate solution might be to allow access restrictions for each report included in an app.
