Does Lowes cut inches off of an unfinished interior door and drill door knob holes in

them? We're looking at doors. I need a 30 x 78, but all Lowes has is 30 x 80 and the cheap ones don't have door knob holes already in them. Will Lowes cut an inch off the top and bottom of the door and drill a door knob hole it in while we're there at the store?
