Add "Pass Thru Fees" to Surcharges & Discounts

I'd love to see an option of "Pass Thru Fees" on the Surchages & Discounts section. Taxes and cleaning are "pass thru" charges for us. While we collect them, we dont keep them so technically not revenue (in our pocket). Ultimately, I'd like to run a report showing: rent, pass thrus, surcharges (pet fee, additional guests, etc), discounts. This would give me a more accurate picture of my actual "in pocket revenue".
