I understand that this is meant to be user selectable? If so, the only choice you have for four priority levels is using a custom field. Otherwise ATS itself supports three priority levels (low, normal, high) which can be set by the user.
Maybe you could combine both features. For example having a dedicated category for extremely high priority issues (let's call it Emergency) and a second category for everything else (let's call it Technical Support). If someone files a ticket in Emergency it's a priority one and you have to respond a.s.a.p. If someone files something in the Technical Support category it's P2 if it's High priority on ATS, P3 if it's Normal priority and P4 (minor bug) if it's Low priority.
