Customer A/R Invoice formula in the total

SUGGESTED

Good morning.

As of 2/11/2024 New York State has implemented a new law regarding credit card fees.  You can no longer note "A credit card processing fee of 3.5% will be added to all invoices paid by credit card."  Now you must list the invoice cash price $xxx.xx and the invoice credit card price $xxx.xx.  Is there a way in Sage to add to the bottom of the customer invoice a formula for the invoice total multipled by 3.5% so that we can now list two totals? Thanks!
