Unique over two fields

Question

Setting a field as unique will prevent users from submitting data that duplicates value in that specific field. Easy enough... but is it possible to flag TWO fields to be unique as a "set" of sorts so say... a specific USERID couldn't submit two reports with the SAME TITLE... but the title field isn't unique because other users might submit a report or purchase a product with the same title?  This would prevent a user from submitting the same data twice... by monitoring the USERID _and_ the TITLE field, as an example. Neither is unique in the table design, but no entry into the table could be the same combination of USERID and TITLE.  I'm rambling and repeating myself, but wanted to make sure I convey what I'm after.
