This has broken invoices for me. A majority of what we invoice is time. The time we bill is not contiguous. We use your time tracking software to make it easier and simple to invoice. For a given customer and billing period I might have 100 time entries. The old invoice allowed me to group the time and add it as a single line item. I now have to individually add 100 items and then go back and manually total them and combine them. WTH. That is not a matter of preference that is broken. What a complete mess.

My feedback to the Developers is revert the change until you fix this.
