Bot difficulty setting for private matches

Really would like a bot difficulty setting for private matches. I know private matches don’t give XP and stuff, just want it for friend matches to practice tactics and characters. It would be nice to have a simple change difficulty setting next to the number of bots with at least a few levels from easy to hard. Hard should be difficult to beat even in a team of a few buddies. Even with pvp private matches it would be good to have hard bots to make the battle more badass!
