Zenworks 11 on Windows 2008 R2 x64

We have 7 Zenworks admins, essentially users of the system. While I can restrict them from certain part of the application (distribution, patches etc) I cannot restrict people from tampering with other admin tasks or bundles.

Is there a way to allow read only access to bundles if they did not create them? For example I create a bundle that is system wide, I don't want others to modify my bundle but they can view the content.

This would be useful not just in bundles but deployment, reports etc...

Thank you.
