XF 1.4 Allowing access to a certain thread

Im having some troubles with one of my categories. I set it up so players can apply as staff under the "helper application" category. I made it so other members cannot read their application since it does contain some personal information. So now only staff can review applications, but unfortunatly this has blocked others from being able to read my Application format posts which is a sticky thread.

Is there a way i can make it so players can view only my thread and not be able to read other players applications..
Thanks in advance
