Currently `date_format` is `yyyy.MM.dd` in [index.lifecycle.parse\_origination\_date](https://www.elastic.co/guide/en/elasticsearch/reference/current/ilm-settings.html#index-lifecycle-parse-origination-date) which is great if you have logs in format like logs-2016.10.31-000002, but since index name is custom and can be like eg logs-2016-10-31-00 that format is not enough, is there possibility to change default date\_format somewhere in ILM?
