BIP Security - Need to restrict user from modify and deleting the reports

Summary:

Hello Everyone,

All the users in our environment have BI consumer role. So they are able to navigate to different folders and they have ability to modify and delete the reports.

We would like to restrict the users from creating, deleting and modifying the report from shared folders. I was able to do it but the issue is users are not able to create/modify/delete reports in "My Folders" folder.

Can someone please help me with requirement where user should be able to create/modify/delete the reports in "My Folders" folder but should not have any create/modify/delete access in Shared Folders. They should be able to only run and schedule the reports available in Shared Folders.
