New Feature wanted About Adding Expenses!

I am hoping the “add expense” feature would be similar to “add earnings” like you get to choose which expense is related to which service you perform. And then deduct that expense when calculating the earnings per hour. Because I found out that the app would use all the earnings to calculate the earnings per hour regardless if the earnings involved out of pocket payment that will get reimbursed which shouldn’t count as an income. I know it does reflect on the total earnings but it’s confusing to see the inaccurate earnings per hour.
