is it possible to add a command to the json which would randomize the skin of items such as furnaces axes picks ect ect ?

I am wondering the same thing.
I like the configuration detail in this more than the Magic Loot, but Magic Loot can spawn items with randomized skins.
Is it possible to do the same for Better Loot ?

Anyone?

Anyone got it to work ... ? We want loot to be skinned !
