Custom Games and Special gamemodes

Hello, I was wondering if you guys would ever bring back the ability to play special game modes in custom games. I remember back in 2014 when urf was released, and I sat in custom games with many of my friends battling it out. I really miss being able to do this. It made urf and all of the other game modes more enjoyable and exciting. I am hoping you could inform me on any information you receive or changes coming that relates to the topic. Thank you.
