Howdy! Is there any Rom Hack Tools to add Stationary Pokemon to Gen V?

[MintySparkles]

Howdy! I'm new to ROM Hacking and this forum in general, I'm in the process of making two Gen V Hacks. I have tools for encounters, trainers, text, even sprite stuff. But I want to know if there's tools for Gen V where can I add Static Pokemon (and adding custom trainers since I'm not sure if I can do that in my trainer editor) Thanks so much for the help.
