Board Columns in TFS

Hello,

I have PowerBI integrated with TFS online, I can get most of the data but I cannot get Board Columns from TFS. We created custom board columns to move our pbis along our process of approved > development > unit testing > qa and the PBIs are moved from one stage to the other. So I cannot see the board column per PBI, does somebody know how to get that data from TFS? If that integration does not exist, can we expect to see it anytime soon?

Thanks
