Ability to restrict user visibility to specific reports

I currently am able to restrict user access to overarching reports (for example, the Statement of Revenues of Expenditures). However, if I give the user access to view that report, they are able to see any and all versions of that reported that have been created/saved. It would be really nice if I could restrict them to only see specific custom reports created within the Statement of Revenues and Expenditures window. Thanks!
