How to restrict a Purchase Order to accept only one type of Project task selection in Fusion.

Can a Purchase Order be restricted to accept only one type of Project task selection.

Ex: if Tasks 20,30 and 40 are core tasks and 50,60 and 70 are non-core tasks of a Project, then on a PO only any one of these tasks should be selectable. and no two tasks from different group should be allowed in same PO.
