S4 Holding Brackets are not useful to be mounted to DIN Mounting Plates

The Holes in the Mounting Brackest of the s4 serioes don´t fit to the holes of the DIN 15560-34: mounting Plate. this mounting is used in many German theaters for a quick change of the fixtures.  if thre are two more Holes in the Mount according to the DIN mouting plate, it would be very nice.
