Replying to Attack 13 Demo bindings - how much room to adjust?

Hey NS, I’ve seen some debates on here about how legit the attack 13 demos are, but one thing I haven’t seen covered:

Can you really use them to switch up your mount point for different days/conditions?

I’m imagining I would mount them so that when they’re slid all the way all the way forward, they’re at true center, then on days when I wanna skip the park and just bomb, I could slide them back. I don’t know that much about demo bindings - I’ve always owned regular ones. Then at first I thought that the toe and the heel piece wouldn’t both slide, but now I see people are saying that they both do.

So is this possible? More details:

Boot size: 26.5
Skis: brand new pair of Liberty Helix 98s

Roofbox seemed to love the helix 98s when center mounted, which would be my park days, and blister seemed to love them for bombing when mounted way back at -7, where suggested by liberty.

Thanks yall.
