Approval workflow for when an invoice amount exceeds the tolerance set

Dear Community,

I would like to know if we can add an approval cycle on the tolerance set for an invoice in case it amount exceeds the tolerance set on the discrepancy between purchase orders and invoices?

Example:

We have a Purchase Order for $100.

Percentage of tolerance 5%

Invoice $106: Approval Required -> If declined then invoice blocked/ If approved then invoice created

If it is possible, where can I find it in the system.

Thank you
