completed development goal notification to be sent only to worker's current assignment HR

Hello experts,

There are employees in our project that have two work relationship in the system, one is employee record and the other one is contingent worker, therefore this employee has 2 HR representatives.

When this employee completed a development goal, the notification was sent to the 2 HR representatives, including the HR rep in his contingent worker record. The business only wants the notification to be sent to the HR rep of the employee record, since it's the employee record who completed the development goal.

Is there a way to restrict the notifications to be sent only to the HR for the Employee work relationship?
