Currently, it looks as if you can create an invoice for each ticket, or you can create an invoice from time entries associated with a particular contact. However, I would like to be able to create an invoice for an account, which includes all unbilled time from any tickets associated with the account. Sometimes I have many different tickets from many account contacts, and I would like to be able to bill them monthly on a single invoice, similar to how we can do it from the Contact "Time Entries" tab.

Is this possible, or am I missing something?
