Can anyone confirm if this feature exists in QB Desktop Pro 2021?

I see the workarounds, however, they don't solve the core issue.

If a customer elects to pay an invoice via QB payments (CC or ACH) then I'd like a convenience fee automatically calculated based on the invoice amount and added to the payments screen.  If they elect to pay via paper check they would never see this fee.  This is basic functionality for other online payment processing system.  Is this a feature in QB and if so how can it be enabled?
