Not in reporting. When you set up billable expenses, you also set up the income account that the customer payment will post to.
In company settings turn on make expenses and items billable
check mark to track billable expenses and items as income
then in company settings>advanced>chart of accounts click the edit pencil and select the billable expense income account
Why intuit separated the two related settings is anyone's guess
So if you want direct and indirect travel to be re-portable, use a class or location or two expense accounts
