I have to build out a somewhat complex JSON file.

I'm using the JsonGenerator object to build out the root structure which includes a array of submissions. I could build out the entire file with the JsonGenerator functions, but this will be tedious and unmaintainable due to the json complexity.

I have decided to

1. store the submission json template in a text file
2. load the text file into a string variable
3. pass the required data into the json string variable.
4. I then want to load the filled out json string variable into a JsonParser object
5. and finally load the JsonParser object into the JsonGenerator object submission array using the AddItemObject function

I'm struggling a bit with the AddItemObject function. 

Is it possible to add a json object to a json array using the AddItemObject function?
