Select Default Class using "Metadata Card Configuration"

Dear Community,

I have Object Type that have 2 Classes.
"First Class" is selected frequently by end users,
"Second Class" is almost never used.

Does anyone knows how can I make "First Class" to be selected by default on new object creation using "Metadata Card Configuration"?
So user does not need to select it every time.

I am not using "Templates" functionality, because creating template adds extra "Mouse Click" to select template when creating new object.
 

I have tried following behavior rules.: 

Using ID's

{
   "Properties": {
        "100":{
            "SetValue":{
               "Content": 8

            }
        }
    }
}

Using Alias:

{
   "Properties": {
        "100":{
            "SetValue":{
               "Content": "FirstClassAlias"

            }
        }
    }
}

 

Using Class GUID:

{
   "Properties": {
        "100":{
            "SetValue":{
               "Content": "2C86E061-4529-4AE0-8EA3-0D5E7C03E6C4"

            }
        }
    }
}

 

Using Class Property GUID and  Class GUID:

{
   "Properties": {
        "CEBF9AC9-C60C-4240-9F50-723DBF3A5CA7":{
            "SetValue":{
               "Content": "2C86E061-4529-4AE0-8EA3-0D5E7C03E6C4"

            }
        }
    }
}

 

In all my attempts Class is not selected by default on new object creation and there is no error message.
