Elacticache default caching

I have a few websites and I just moved to AWS. I managed to force installer to install DB on RDS now so whenever I do “create” command it creates RDS instance instead of localhost so I could uninstall MySQL locally.

Now for the best performance I want to move to elasticache. When I do create new website though there’s no way to change memcached to remote one (no setting in EE config). Is there a way to do it? Kind of tired of changing it manually each time. Ideally I’d uninstall memcached on the server too.
