GraphQL: whether can support to class create mutation with a new subobject install of only a pointer

[jackeryjam]

Sincerely thanking for bring such a wonderful function(parse + graphQL) to us. I love it deeply.And when I use it, I also meet some question as follows.

If I want to do this, first step I should create the a record of the pointer class and write the object id to it, where can I write the pointer class content in it to implement create the father class record and create the son class record at the same time only with a graphQL mutation.Like the following picture.
