Index settings file

Hi all,

I know it's possible to store mappings in individual $ES_HOME/config/mappings/[index_name]/[mapping_name].json files, but is there a way to store all mappings in a single file for a given index?

Basically I just want to have these index settings stored in a file instead of using the API. Being new to ElasticSearch, I don't see how to do this.

Thanks!
