Projo already has the unit “hour (manual)”, which, regardless of the billing rates set, charges at an hourly rate entered as a unit price. However, the hours are not automatically drawn in invoices and the hours do not appear in the “time journal” attachment to the invoice. There should also be an “hour (fixed hourly rate)” unit, which automatically adds all hours (regardless of who booked them) and also creates a time journal for the calculation - but multiplied by the fixed unit price per hour
