I totally agree. This really annoys me - especially when I have my perfect marquee selection and I move something to another storey by cutting and pasting. Doh, lost my marquee.
Possibly instead of having a second marquee for pasting, maybe the whole copy and paste function (to different storeys) could be better designed/managed. Maybe an option to "Move Object to storey...".
Or maybe an aditional option in the change all selected elements dialogue box, so in adition to layers and pen colour (and the list of selected element types) there could be a storey option there as well. This would of course be an alternative to the cut and paste.
Would be very handy.
