Bugtracker does not allow client users to see the 'Classification' on the Bug list

On the bug list page, client users do not see the 'Classification' as a choice when they customize the column. This field is valuable to them. They can, however, filter based on classification but has no way to see them on the list. They can see the classification once they click on a bug to see its detail. So, clearly this information is not meant to be hidden from them. It is just inconvenient to view the list of a certain classification (e.g. they want to see all 'new features'.)

On the contrary, client users can choose 'Flag' in the drop down list for Customize Columns. However, when they choose to see that column, the column is not shown. This seems like a bug. Also, client users can only see External bugs by design. The Flag column will be meaningless to them even if they see its data (as it will always be External.)

So, can I propose a swap between the 'Flag' field and the 'Classification' field on the bug list for client user?
