Stop submitting Invoice when the Invoice Line amount is too high than PO line amount

Summary: We have a situation where users incorrectly enter Amount in place of Quantity while creating an Invoice [ on Invoice Line ]

However, the system currently throws a warning message, and users ignore the message and submit invoices, this is creating a lot of manual correction for the AP team.

Can we stop the user from submitting the Invoice when there is too much discrepancy between the Invoice Amount VS PO Amount?

Like grey out the Submit button / hard stop with warning?
