You can drop down to the collection level and do a bulk update. This action will not be atomic - some of the writes can fail and others might succeed - but it will allow you to make these writes in a single round trip to your database.

It looks like this:

var bulk = People.collection.initializeUnorderedBulkOp();
bulk.find({}).update({});
bulk.find({}).update({});
...
bulk.execute(function(err) {
    ...
});
