Of course.

Your level has a ymin and a ymax.  ymax-ymin equals your height.
do a loop, instantiate your object, and then translate each subsequent object in
the y direction by the incremented height.

#declare Ymin = min_extent (Object).y;
#declare Ymax = max_extent (Object).y;
#declare Height = Ymax-Ymin;

#for (Level, 0, 5)
     object {Object translate y*Level*Height}

(untested code)
