Yes, just shoot 24pN and make sure that you have the "remove 3:2 pulldown" button unchecked in the options tab. Then just start a regualr 60i timeline and edit it like 60i video. The 24pn footage will still be progressive as the even and odd fields will be displayed as a single frame, much like if you make a progressive DVD and play it on an interlaced monitor. Easy as pie.
