List Form JSON Format - Body section width

[Paulo Romualdo Junior]

Hi! 

Is possible increase width of column in a section?

e.g: 2 sections of 3 columns and 1 section of 1 full width column?

The goal is the section named "DESCRIPTION", display in full width, and not 1/3.

{
    "sections": [
        {
            "displayname": "SECTION ONE",
            "fields": [
                "Title",
                "Field01",
                "Field02"
            ]
        },
        {
            "displayname": "SECTION TWO",
            "fields": [
                "Field03",
                "Field04",
                "Field05"
            ]
        },
        {
            "displayname": "DESCRIPTION",
            "fields": [
                "MultLineRichTextField"
            ]
        }
    ]
}

Thanks!
