Instead of "Make Invoice" pushing all unbilled ticket items to an invoice, it would be very helpful to have the ability to tick the items you want to bill and then push to invoice. I realise that I can currently edit the new invoice and push line items back to unbilled on the ticket, but we have some tickets that have hundreds of hours on them and to be able to select the line items to be invoiced before "Make Invoice" would save a lot of time removing the unwanted line items from the new invoice.
