Restrict PO limit item creation if exceed PR amount

[SAPSupport]

When processing a purchase requisition limit item to a purchase order via the 'Process Requisition V2' app, users can create multiple purchase orders referencing a single purchase requisition, causing the PO value to exceed the PR value. Is there a way to prevent users from creating purchase orders if the cumulative amount exceeds the referenced purchase requisition?
