i would like to see it as well, though i have both now so i'm not gonna switch my 500 just for that.
In fact on my first use of the 700, making doors, the mortise was either at the level of a rebate for the glass windows, or at the level of a panel groove. Rendering the pins useless because they didn't extend far enough. So i had to mark every mortise by hand. And i suspect this will be the case very often. It's certainly better now, but not not yet good enough.
