I am just starting these courses, but I know that I will eventually be adding a piece to our DB that I believe will be incorporating this Map Overlay.  Similar to the restaurant table or cemetery plot maps, ours will be floor plans showing beds/portions of rooms of our residential facilities.  I am hoping that the boxes that are placed on these maps can contain links to the beds (queries?) so that the data displayed can change as different residents are assigned to the different beds.  I will also need to learn how to increase the number of boxes available.  Can you please confirm that these options are possible?
