Do _what_?  You can place a score multiple times with its distribution
across pages being different every time.  When do you plan to take
action for "detecting if the current page was the first or last page of
a score" when each copy of the score will have a different page
distribution?  This action can then not be part of the score proper
because it has to be different each time.
