Is there a way to access the parent index inside of a nested array?

I have a bard field with a nested list field and I want to access both the list index and the bard block:index from inside of the list array.

{{ blocks scope="block" }}
<div>
{{ list }}
    {{ index }} - list index
    {{ block:index }} - empty
    {{ block }}{{ index }}{{ /block }} - still empty
{{ list }}
</div>
{{ blocks }}
