I need bot commands for lobsiding teams

I want to set up a server for me and my friends where its us 4 verses 9+ bots.
I need commands that:
* Restrict bots to one team
* Allow unbalanced teams, so I can have 4 vs 9+
* Add more than 9 bots (if possible)

Thanks in advance!

The easiest way would be bot_vs_human and bot_number*
For your example of 4 player vs 9 bots set bot_vs_human to 3 and bot_number to 9
*Although the documentation says: "Minimum number of bots" in this case it acts as the upper limit for the bots.
