Add new key into data group without updating entire list using the API

Excellent. Add and deletes are both working. Thanks again!

  this is cool, and I had no idea this worked. What versions have you confirmed this on?

Hi  ,

I just ran a test on versions 14.1.2.2 and 13.1.3.2 successfully.

Best regards.
