Save variables from resolver for later use

I used graphene for my project and it worked quite well, but I had a really tough time modifying json response, for example adding count of total matched records. I read documentation, but it seems to be overly complicated, which resolves in duplicate responses to database, and hence slowing processes. I am working with quite large data, so duplicating responses to database is not an option. It would be very helpful if I could save some parameters from resolver to separate dictionary to later modify response. I think adding this feature would simplify workflow for many, who wants to use graphql in their projects.
