You can manually choose a horse but I'm not sure if you can set an upper and lower limit for each individual horse with the v2 bot. The v3 bot may do this as you can use multiple strategies.

Have a look at their website. They have manuals for each bot and settings and you can trial the bots for free for a few days.
