limit the Field against attribute to a range of values

Hello,

Is there a way to limit the field against attribute to a range of values regarding the work item type.

My problem could be summed up like this. I have 2 types of work items : A and B. I have 3 categories : 1, 2 and 3. Can I limit the choices for the fields against attribute to 1 an 2 for Work Items A and 2 and 3 for Work Items B.

In my template, a Work Item B in category 1 doesn't mean anything at all and I would like to make it unavailable for users.

Note that I need to control category with this attribute to select a possible list of owners.

Regards,
Sylvain
