Hi Robert,
The only way that I can see to do this would be to use the following **(you would certainly want to be careful here not to give too much access)**;
Subscribers > Class of Service > System Access Page
Class of service system access settings specify which tasks, if any, subscribers including other system administrators can do in the Cisco Unity Administrator. You can customize access to Cisco Unity in several ways. For example, you can deny access to the Cisco Unity Administrator, or deny access to specific pages in the Cisco Unity Administrator, such as COS, subscriber, or distribution list pages.
When you deny access to specific pages in the Cisco Unity Administrator, the links for these pages are disabled for the subscriber. Alternatively, you can specify read, edit, add, or delete privileges for these pages, or can allow subscribers access to subscriber pages only for the purpose of unlocking subscriber accounts or changing subscriber passwords.
**Public Distribution Lists Select the applicable settings for subscribers assigned to this COS:
Read: Check this check box to give subscribers read-only access to the public distribution lists pages of the Cisco Unity Administrator.
**Edit: Check this check box to allow subscribers to edit the public distribution lists pages of the Cisco Unity Administrator.
Add: Check this check box to allow subscribers to edit the public distribution lists pages of the Cisco Unity Administrator, and to add new public distribution lists.
Delete: Check this check box to allow subscribers to edit the public distribution lists pages of the Cisco Unity Administrator, and to delete public distribution lists.
