Dear Grr82CU -
I'm very glad that you're enjoying our community! It's great to hear that you are making progress towards your publishing goal.
When I do my submissions, I tend to think of them as a bulk download. So I give them my entire work, in its current state. Then in 2-3 years I give them a fresh copy of my entire work, in its new state. I don't try to figure out which specific areas were altered, that would seem quite a challenge to me!
