@lubos, in the Billable Time module is it possible to add a status “Not billed” ?
Use case:
I have a time registration app and export all hours into the Billable Time module in Manager. Some hours are billed and some are not, and the Written-off status does not seem suitable for the hours which are not billed as the Written-off status is used for Billable hours. The reason all hours are imported into Manager is because it is simpler and Manager seems like a safe storage of hours historically and also for the non-billed hours which are used in calculation in the Payslip module.
