Pretty much as the title asks...are there any cheat codes or mods that let you add or pick a specific champion?

E.g.  Cntrl+XXX

.AddChampion("arcturus"), which then looks in the pool of champions that it would draw from when fame hits the correct level anyway to see if a champion with that name exists, and if it does, then spawn it on the map as a champion in the sovereign's faction, just like the leader had picked them normally?

I have favorite champions that I always want in my games, but unabashedly save-scumming has taken years off my life.

Does anything exist like I'm describing, or is this a bridge too far?

You would think the devs would have built a command into the API, if only for their own sanity during testing...
