Mandatory 'Type' field in the Knowledge Bank

When attempting to set the Call Type ('Type') field in a Knowledge Bank template as mandatory, we found that it could not be done.

I'd like to suggest that the ability to make the Type field mandatory be implemented, as the Service Window (quick-searching) functonality relies on it as a type of matching. I've also seen many instances where the Type field has unfortunately been left as 'Unspecified', which adds no value to the knowledge bank articles or tickets for that matter.

I understand that 'Unspecified' itself is a selection and therefore would bypass any mandatory setting, so this is another issue that would need to be worked around.
