Can't set a custom field to required in "get support" type, but can in "bug" type

[Robert Kowalewski]

Hi,

I have added a custom field (select box with 4 options) to the request form. I would like to make it mandatory/required when a portal cuostomer raises a request. This is quite possible in the request form for the issue type "bug" but not possible in the form for the issue type "support".  Am I overlooking some special setting for the issue type support? Could be, because I can not set any other field as required besides description.

Thanks in advance for any ideas.
