Only Sync Permissions and Not Other changes

Is it possible to only synch some difference types?  For example, after doing a comparison of all tables in my database it finds tables that have index index and constraint issues as well as difference in user and role permissions.  If I generate a script for those tables it will include all of those differences.  I would like to be able to generate the script to synchronize the permission differences, and ideally only sync for a give user or users.  Is that possible?
Thanks@
