How to remove documents from multiple collections in one query in MongoDB?

It‘s an old question from How to remove documents from multiple collections based on ID in MongoDB? 2 years old.

If there is a solution?

My scenario is :

Collection A:
_id,
name
Collection B:
_id,
name,
aId,
Collection C:
_id,
name,
bId,

A vs mutiple-B
B vs mutiple-C

I want if there is a single query to delete docs by aId: XXX. such as:

db.B.find({"aID":XXX}).foreach(
   function(b) {
     db.B.find({"_id":b._id}).foreach(
        function(c) {
           db.C.remove(c._id)
         }
     db.B.remove(b._id)
   }
);

db.A.remove("_id":XXX)

But it is two querys, Is there a better way?
