Yup it does. I would suggest "fancying" each level in its own file first and then apply an isometric "tilt" to them (just make sure that you use the same angle). I do not know PS so I can't tell you how that would be done, but I think it would be obvious when you see it in the menus. Once you have that, place them in the same PS file for lining up as I described above. You might have to fiddle with the views a bit to show some lf the walls if that is where you want to go...
