You could try and call the Game and Fish, last year i was a party member and had to switch to a different party due to too many applicants in one party so I had to withdraw and then reapply. It was real easy,you just loose an application fee.
Log into the G&F website and go into the apply for a license section. Once you get to the page where you can choose licenses, at the bottom of the page it has a link to view already applied for licenses. Go into that and you can edit your applications.
