How to provide options_file for ycmd?

[ChoppinBlockParty]

ycmd has an option --options_file that is a json file with a lot of helpful options? For every ycmd start it is suppose to be created once, because of an HMAC secret inside. How does emacs-ycmd is handling this? Can I provide a file with my custom options for this? Should I handle this manually in my emacs configuration: creating a temporary file from a template, and providing as an option to ycmd-server-command?
