I can pick any I have available, but I cannot create my own at all? That’s pretty bad. I am limited only to the official content, I presume?
Homebrew and custom content are on our roadmap for the character tools, but are not something we have implemented as of yet.
We have big plans for homebrew, because we know it’s an essential part of tabletop roleplaying games! In the meantime, only the official options are available.
