Ability for Tamed Wolves able to track things down.

I know the Sniffer exists now, but I feel like it would make sense for wolves to be able to sniff something, rather that be in your hand or on the ground, and be able to lead you to it. This would be useful to better find buried treasure, lost items, generated structures, etc. To separate the two mob's abilities, I think the sniffer should just be able to tell you a general location and wolves could lead you further to it once your in the general vicinity and dig for you (as dogs would do).
