This is a problem but I have developed this workaround: In Quickbooks I created a customer called "General Time" and another called "9552 Installation" which is a more expensive and seldom-used rate. Our WC carrier will allow us to apportion the employees' time providing there is real-time time-card record keeping. In Tsheets (Quickbooks Time) they select the "customer" when they log in. It's a bit cumbersome to generate a report, but in Tsheets go to Reports/Itemized Total Time: then customize the report to include the "customers" you want to include. This generates an Excel file but when printed it looks fine.
