Pretty sure there's nothing new on this topic, but I thought I'd bump it just in case.
We just had a building official complain to us about this exact issue. We changed several (actually a lot of) items in our Opening Schedule and the official is complaining that they can't tell what changed. We added a (AD#3) in the comment field (manually, of course) so they could at least see which lines have changed, but they want us to tell them exactly which field changed. Specifically, he wants to know it the Fire Rating is different.
As several people mentioned above, we could put a Revision Cloud on the sheet but that's not only labor-intensive and prone to error, but will actually be
wrong if the number of lines change.
As of the Subscription Advantage Pack, we can color-code the field in the Schedule View, but that's not going to help when we print it for the Code official.
I doubt that there's a fix yet, but it the Factory is listening, this is still an issue. And, now that
I'm having a problem with it, it should be a top priority!
