Enable /data get to obtain a value using both NBT path and number in order

In advance, sorry for my English.

Sorry for the dumb title, minimum 75 characters. Recently discovered that /data get allows players to get an NBT value using paths such as "Items[0].tag.Weight" and "Items[{tag:{Enchantments:[{}]}}].tag.Weight", however, there is no way of combining the two. I can understand if this sounds like gibberish, i can't find a good way to convey it. I've tried to give an example below.

If i want the Weight value from only an enchanted item, i can do that. If i want the Weight value from only the first item in the chest, i can do that. If i want to specify both an enchanted item, but also the first item (Combined: The first enchanted item found in the chest), i can't do that.

As of now, this is limiting the amount of things that could be done via this command a lot, but also projects that use it as a whole.

I can't imagine this would be hard to implement, something as simple as "/data get block x y z Items[0,{tag:{Enchantments:[{}]}}].tag.Weight" could do it, although i'm not a programmer, so sorry if it's actually impossible.

I feel like there's missing functionality with array subscripting in NBT paths. You should be able to define compound tag predicates at array subscripts like:

data get <source-profile> Foo[0]{Bar:"Baz"}.Bar

This will access the first index's Bar tag of the Foo compound array only if it matches the contents of the compound predicate.

However, this will not try to "find" the first available element, instead it really just operates on the "first index" only. Still, there are ways to filter out a number of elements of an array though.
