[Feature request] auto brackets in set_nbt function

[Sn0wix]

Hello there,
I recently had a problem with loot table function set_nbt. When I created my loot table and loaded into a world, it said Couldn't parse element {element path} - Not a json array.
I solved it with adding curly brackets {} to the tag.

So, the feature I would like to request is automatically generating brackets, because when someone like me tries to set the nbt, it won't work. And it could also check, if the user has already added the brackets, so the more experienced users don't get confused.
