With this Mod Pokemon Trainers can use any Pokemon in their Party as their lead (except the last one, which is usually their signature Pokemon).
To install, just drop the file into the folder "[Pokemon Reborn]\Data\Mods". You might need to create the folder "Mods" first, if you have not installed any other mod yet.
