There are very few options at the Department Level as compare to the Location Level. Adding many of these options (all) to the Department level would give a lot more granularity and control over WHD.
An example:
WHD allows all clients in a Location the ability to create a ticket by sending in an email.
What I would like to end up with is the ability of on-site people to be restricted to using the Web Interface to create incidents, and those who are mobile (our sales force) to be allowed to send in incident via email.
The Sales force are all contained in the various Locations' Sales Departments.
Having the ability to control the "Create Email Incident" option at the department level would allow this to be done.
