Setting up frequency for quality analysis

Hi

We are planning to use quality module for PO receipts. However would like to setup periodic tests for supplier/items combination, with different frequencies. For eg, need to do quality test for every 10th PO received from specific supplier. So when we receive PO , system should prompt quality test revision screen P3711 for  1, 10, 20th PO received from that supplier.  Understand that enabling test results is like all or nothing for item or item/supplier level.

Appreciate your inputs to achieve this periodic test setup with different frequencies.

Thanks
