Custom games vrs BOTS needs improvement!

I was playing a custom game vrs bots the other day so that i learn how to play kalista. First problem is that it wasnt specified in which lane and which role each enemy and friendly bot would go. Also what summoner spells they would have. My support at one game, kept hitting the cs and didnt let me farm. I think that you must change is so i can assighn a role to a bot, also what kind of summoner spells they have. Next i wanted to mention how the intermediate dificulty isnt enough. In many occasions the bot could have killed my but they retreat as soon as i poek them allitle. I was hoping for more challenging bots, that could make smarted plays, even turret dive you if their hp and lvl allows them to do so. Maybe even do dragon attempts.
