Add dictionary item to an existing list item

I’d like to be able to add a dictionary item to a list item.

For example:

my_list:

  • first_list_item:
    color: blue
    country: us
  • second_list_item:
    stuff: blah

What I’m trying to do is add to a list item like adding “state” below to the first list item.

my_list:

  • first_list_item:
    color: blue
    country: us

state: va

  • second_list_item:
    stuff: blah

I’ve used + to add a new list item. I’ve used combine to add a new dictionary item. But combining them seems to be eluding me and I’ve not found a solution online yet.

FYI, I’m using with_nested to compare two lists and determine what should be added to which item. That part is working. it’s the set_fact part that I can’t seem to work out.
