Hello Team,  
Thanks for your valuable time.  
In my entire current ELK setup everyday some new changes needs to be performed on grok patterns and to avoid any human mistakes during changes , I want to use lookup file which will contain grok for all indexes, I know it sound weird, Ultimate aim is to simplify configurations, Please suggest me good other options as well.
