I need to set initial value for issue due date automatically based on which project or tracker the issue is created. I'm sure there is a plugin or functionality for this but I just can't find it. I found issue due date plugin, but the description doesn't quite match. Basically I just want to set due date two days from now if tracker is support and something else otherwise. Understanding workdays etc. would be nice, but any possibility to set due date automatically would help.

Am I just missing a thought or keyword here?
