Register playfab user does not receive info request params

When registering a player to playfab I would like to receive some data in the same call (so we don't have 5 calls where we could use only one). I noticed on the Register Playfab User call that there is the option to ask for Info Request Params but no way to receive them with the response (in the Login Result there is the InfoResutPayload to get this data, but not on Register).

And just to clarify things, I want to receive Title data, there is no point on asking other data because it is not initialized yet.

Sorry if the question has already been answered, but I couldn't find anything on this.
