We're using osTicket V1.9.3.We have a field called Billable on the ticket form (Ticket Details section). This field can be changed by different users when they edit the form. We want keep track of all changes to the Billable field (see attached file) Looking at the database tables, ost_ticket_thread saves tickets' history. Can the Billable field be added to this table? if so can you provide some guidance.Thanks
