Portal Created Initiation BR w/ Bots but only friends?

Hey!

Just trying to create a Portal like Initiation BR with the bots, but so a group of friends could play by and against themselves in teams of two. Seems I can't add bots to BR creations. How can I create something not far from that original?

Or, if you know of a similar Experience, please let me know what name or number to use.

Thanks!
