PowerDesigner (Database design) - add PK to cross-reference table

i would like to know how to add PK to cross - reference table which is created from converting Conceptual Model to Physical Model and associate it with other table as FK.

Conceptual Model

Physical Model

Expected Result

Physical Model

• Job Applications Table : PK ja_id(int)
• Applications Table : FK ja_id(int)

I think i've described my problem clear enough :)

Thanks for help !
