Pay milage expense with undepositied cash

Pay milage expense with undepositied cash

Hello
When I add millage, the only probable option to "pay through" is Owner's Equity. I pay for the fuel using undeposited cash but I can set "paid through" to undeposited funds while entering mileage. I do not have employees and this is the mileage that I use for business travel.
I would like to add a mileage for which I paid through undeposited funds.
Thanks.
