JSON navigation for grid

[env0ke]

Hi all

I write REST API and his return json format. For example:

[
    {
         "first_name": "John",
         "last_name": "Smith",
         "location": {
             "country": "Canada",
             "post_code": "12345"
         }
    }
]

How i can navigate to "country" and "post_code" in my Grid (or model for Store)? If i write name for field "location.country" or "location['country']" id don't work. Sorry of my bad english.
