8 – Splitting routing.yml into multiple files

I have a mon_module.routant.yml file and because of I have multi entity in my module sound too big and not pretty.

Is there a way to split it for each entity and include it in a file like symfony, I use the code below but it does not work in drupal 8.

resource: "@ acmeDemoBundle / Resources / config / routing / user_routing.yml"

I'm also using the absolute path for the yml file but it does not work.
