[FE15] Editing recruitment with Paragon?

Hi, I’m new to all this, but is there a way to recruit other characters like the bosses or generics??

The two things I’d really like to do are add characters to existing recruitment events and, if possible, maybe add new recruitments (perhaps at the end of a map or something). If anyone knows how to do this (or if the second one is even possible) please let me know.
