Invoice custom total amount Surcharge

We need our invoices to be split in two currencies for example 90% in one currency, and 10% in another currency.
I was able to customize the invoice and utilize the surcharge custom fields to show these percentages with the currencies requested. However, the total amount of the invoice sums the total amount and the surcharges as well.

Is there a way to make the custom surcharge not summed in the total amount?



Sorry, that isn’t supported.

One option may be to use a custom invoice field rather than a custom surcharge.

I am already using all of the 4 custom invoice fields.
Is there a way to add more than the 4 custom invoice fields?

Sorry, it isn’t supported.

One option may be to use a multiline custom field to combine values.
