Adding bots in the mission editor ?

All the threads concerning adding bots, describes how to add bots with a script. I'm wondering if there is the possibility to add a bot with the mission editor. When I launch the mission editor I can't found the player shapes in the shape directory, only in the static shape directory. There is not the possible to add a function to a shape. If I need to position a bot to a specific place how will I do that ??
