With Pages (which I believe is what @erwblo is working with), you can choose the target - either a modal or replace the current screen.
I just did a quick test of this idea, and it kind of works. But the problem is that if the user cancels out of the Edit screen without doing anything, then they’ll be left on the Form screen - which I believe isn’t what @erwblo would want.
I think to make this idea work, you’d have to use Show New Screen for the Edit screen, and essentially build a Custom Edit screen. That way, you can control what happens if the user cancels (probably 2 Go Back actions). But even then, I’m not so sure how well it would work. Seems very fragile to me
