Create your own collections with objects for repeating sections in the document generator

You can already use collections with objects from start forms in the Nintex Document Generator action for repeating sections. But if you create your own collection with objects inside, it's not possible to refer to the properties of these objects in the Nintex Document Tagger.

If I have the following collection that's not created via a form, I want to be able to use these objects and properties in a repeating section.

[

{

"fruitName": "Apple",

"price": "1$"

},

{

"fruitName": "Orange",

"price": "2$"

},

{

"fruitName": "Grape",

"price": "3$"

}

]
