I often have many tickets for a customer. When some repairs are complete and I make an invoice, it's very tedious to search the list for the completed tickets. It would be nice if the list was sorted by ticket and each item had a checkbox next to it. That way I can tick off the items I'd like to be added to the invoice. For me it's rare that add all is appropriate. And, it takes so long to add each item and then have it refresh. Sometimes my tickets have 30 or more items on them.
