Build Permission - Edit and Save Report Copy Doubts

Hello everyone,

I have been reading about the Build permission and the ability to copy a report to another workspace, but I cant really find an answer to my question.

Is it possible to grant Build access on the dataset level (not on App level) which will give the possibility for Viewer Roles (with addition of Build capability) to save a report to another workspace (i.e: their My Workspace) and not be able to Edit the current Report?

I would like to grant the possibility at workspace level for my Viewer Users to save the report other workspaces so they can do their own analysis on top of my existing report, but not incur the risk that they will edit the original report itself.

Thank you!
