where I'm taking the 'id:' field from each record and inserting an underscore and the id into the 'attributes' label directly above.
Any takers?

I use awk instead of sed...
Reverse file order, perform changes using awk and reverse again
tac test.yml | awk '{if ($1=="id:"){idtag=substr($2,2,1)}; \ if ($1=="attributes:") {print "attributes_"idtag":"} \ else {print $0}}' | tac -
---- That was awesome...thanks...I learned a lot there.
I had to adjust the length of the substr function to get what I needed.
Thanks
