JSON Object in Adobe Campaign Standard

All, 

I've been asked by my client to create Object as part of the Event for a Trigger. When I tried to create it under Collection, the API preview shows that it's a List (Array) vs Object. 

 "shippingAddress":[
{
"shippedFName":"string50 #1",
"shippedLName":"string50 #1",
"shippedAddr1":"string100 #1",
"shippedAddr2":"string100 #1",
"shippedCity":"string100 #1",
"shippedState":"string10 #1",
"shippedCounty":"string100 #1",
"shippedPostalCode":"string25 #1",
"shippedCountry":"string50 #1"
},
{
"shippedFName":"string50 #2",
"shippedLName":"string50 #2",
"shippedAddr1":"string100 #2",
"shippedAddr2":"string100 #2",
"shippedCity":"string100 #2",
"shippedState":"string10 #2",
"shippedCounty":"string100 #2",
"shippedPostalCode":"string25 #2",
"shippedCountry":"string50 #2"
}
],

Is there a way to create the Shipping Address as an Object?
