Since Bento packed up about a week ago, I'm trying to recreate a feature from Bento, whereby I had a few fields (like portals) in my invoices in which I could choose a number of time records, expenses, etc. relating to a specific project, sum them and I could then add time based fees to fixed fees to produce a final sum to invoice.
In Bento it was very simple and intuitive. I would have thought FMP would make this easy, but I've tried everything I can think of and I'm left pulling out what's left of my hair.
I attach a screenshot of what I'm talking about from Bento.
