the same approver repeats is there anyway the notification go only once since its the same person

Summary:

We configured our PO approval rules based on the cost centers and PO amount but we face the issue now if the PO has multiple distributions with different cost centers the notification will assigned to the same approver twice so my question is is there any way to go only once since its the same person,

for example, the attached PO includes multible distributions with different cost centers and regarding to our approval matrix :

1) if the cost center equal (050) and the PO amount greater than 800 EUR--->Approval#1:Emp1 & Approval#2:Emp2 & Approval #3:Emp3

2) If the cost center is in(123,230,133,220) and the PO amount greater than zero EUR ---->approval#1: Emp2 & Approval #2 Emp3
