[Contextcapture] Web viewer 2.0 multiple models

How to add multiple Models to web viewer?

I see that config,json contains list of models

{
	"units": "metric",
	"url": "../Scene/3dtiles.json",
	"name": "3dtiles"
}

but if adding additional models then there is error "Failed to load root of dataset"

{
	"units": ["metric","metric"],
	"url": ["../Scene/3dtiles.json","../Scene/3dtiles.json"],
	"name": ["3dtiles","3dtiles"]
}

This syntax gives different error "No dataset is specified"

[{
	"units": "metric",
	"url": "../Scene/3dtiles.json",
	"name": "3dtiles"
},
{
	"units": "metric",
	"url": "../Scene/3dtiles.json",
	"name": "3dtiles"
}]
