While I was in Montreal for the Six Invitationals, I worked on this feature during Group Stage.
Today we pushed it to the live system for CS:GO. You are now able to create an own mappool for your mapban Lobby. It won’t be saved and if you need to create more as one Lobby you will need to do it serveral times, but it’s a first step in the right direction.

This Feature was made possible thanks to the first implementation of the API. We needed to recreate the way our system handled Maps and Mappools, so we directly created it in a way which will allow us a high flexibility in future.
