search for wolves with N special markings

Just like we can search for a tier II base in wolf TC search, I'd like to be able to search for any special (non-customizer) markings! Preferably various numbers of them.  The best way to implement that would probably be another line under the marking color/type lines, where you could pick the minimum marking tier and how many markings you want.  The idea is to be able to search for things like "wolves with at least 5 special markings", which would be really useful for me right now, since I'm looking for a future breeding male.
