Sorry for the thread necro, but "me too" - It's sort of a bad UI/database management design to not have some sort of control over which character you assign to a particular "dash".
I actually deleted both by -1 and -2 "slots" when I was experimenting with the website, not knowing I could never get those numbers back.
My played -1 and -2 are alive and well, and accumulating hard copies of their chronicles, which are being credited online to deleted characters.
