Tiefflieger

If I create a PQ it isn't possible to "find" more than 500 Caches/PQ. This is a kind of problem in bigger cities like Munich (more than 500 in a 20km radius) because you have to create several PQ with a very short range. Isn't it possible to change this limitation for premium members to a number like 2000 by the Groundspeak programmers? I think this would be very practicable.
