Discover/Saved Search - Choose to display only a few of the fields in nested object

Hi,

I have documents in an index, say parent, which one of the fields is an array of another type, say child.
I want to now select just a few of the fields in the nested documents(child) in Discover and save it as saved search. I want to embed this search in dashboard, so that I can see the matching nested field (child) values when I filter on fields from "parent" documents.
In Kibana, I could only select the array field but not the fields within the array/child. Any suggestions or is this a known limitation?

Thanks,
Siva
