Thank you for contacting us.
You can achieve this by setting the permissions of the module. Go to "Permissions" of the dynamic module and there you can set View, Create, Modify, Delete, Change owner and Change permissions settings according to your needs.
I sincerely apologize about my previous reply, but now that i have made a deeper research it turned out that permissions for items is not supported yet for dynamic content items but will be soon. And the permissions of the dynamic module I told you about are for the backend only.
If you have any other questions, don't hesitate to contact us/me.
The global permissions for the module are located in Administration->Permissions->YourModule in the left-hand menu.
Was that PITS ever implemented/chosen?
