Asset Sources Usage

[Nahere]

With Multibound 1, I could subscribe to various quality of life mods that I wanted in all my instances and include them with a blank blacklist like so:

"assetSources" : [
		{
			"type" : "workshop",
			"blacklist" : [
			]
		}  
    ]

Is this still possible in Multibound 2? Also is there any documentation on the instance.json format anywhere? I notice windowTitle doesn't seem to do anything anymore.
