No. Sorry. I have not found a solution. And the story gets worse. Some in this thread have said that Price Rules work in Invoices and Estimates and that is true - in the old layout. I tried switching to the new layout and guess what? Nope. No more Price Rules. They do not work. I think that was stated somewhere else but I validated it to be true. So the software engineers are once again dictating what they think is best without listening to the folks that need to do the work. You and me...
