Confirm Receipt functionality with mutliple expected delivery dates

My question is related to how the confirm receipt functionality will work with a Po with multiple Po lines and different expected delivery dates on those lines

Scenario:

- If a requester has a large purchase order (PO) with PO lines 1-10 and an expected delivery date of December 1st, they should receive a Confirm Receipts notification on December 2nd if those receipts are not created.
- If no action is taken by the requester on the initial notification and reminder notifications for PO lines 1-10, and three weeks pass, then PO lines 11-20 on the same PO have an expected delivery date of December 15th. If no receipt is created, they will receive a Confirm Receipts notification on December 16th.
