Is it at all possible to get a new roll that you can only use if you have a class that can use said piece?

Kind of annoying in a PUG for weekly savage runs when you have to go as a different job, the item you want drops, and someone who hasn't even unlocked the job out rolls you on greed.

Sure, I could wait for a different party that allows me to join as the job I want, but sometimes a party you join "can't find a tank but plenty of dps" so you take one for the team and get screwed in the end.
