What I commonly do is pull up that particular old visit under "past encounters," use the left mousee click-and-hold, then highlight the area I want to use, then <CTRL>-C, go back to my current visit, and then <CTRL>-V to paste it in.
It's not the elegant with that Leslie is wishing for, but it's a little work around that I use quite a lot.
But I like Leslie's idea for future upgrades.
