Allow the portion of a donation/gift that offsets the processing fee to be applied to a separate giving fund - we use "Help Offset Processing Fees" - instead of applying it to the total gift. Ex. Pledge $50 via CC. Instead of $51.80 reflected as Pledge donation, have it split $50 Pledge, $1.80 Help Offset Processing Fees. This "offset fund" would be a global option that could be included in general settings.
