Document filtering using custom elements

[Graham]

I am trying to capture business needs and the company / department responsible for delivering them, I'd like to produce business needs documents for each of the responsible parties.

I've created a custom 'Business Need' stereotype with Responsibility as one of the attributes.

I've managed to produce seperate documents by putting the responsible party in the Keyword attribute and using document filters to filter on Keyword, is there a way of using filters with custom attributes, i.e. my 'Responsible' attribute?

Thanks
