With AFPex it will add IFPS if the origin is indie that zone. Outside, then you add the addresses ZPZX and ZTZX as standard. Some airfieds though require ZQZX to be added. CAP550 will cover all your needs though.
Do you use a system to validate your route when inside the IFPZ ? Or do you just fire it into the test cell ? What about routes outside IFPZ, how do you validate them ?
