Need to hold a AP invoice based on comparison between Matched amount and Invoice amount

Summary:

Hi

We have requirement where we need to have a mechanism in place when a there is an invoice with a different matched amount and invoice the AP invoice should be Hold.

Example :

AP invoice amount 5000

AP invoice line # 1 amount - 4500 matched amount - 4500

AP invoice line#2 amount - 500 matched amount - 0

This invoice will get validated as the invoice amount matches the invoice line amount , but our requirement here is to compare the total matched amount with invoice header amount if this comparison is not equal then this invoice should go on a hold.

Can we do such validation using Sandbox (Page composer/Application Composer) ?
