Dunno if it's feasible, but would it be possible to add pet tracking for auras (similar to this)?

For example, Beast Cleave would be nice to be able to track on Multi-Shot (As a BM also rely on that for AoE Kill Command).

I'll think about this more in general but you don't need it for Beast Cleave (at least on retail) as it puts a buff on you that will already work, as well as a buff on your pet.
