Ahhh good ol donjon, I should have guessed. Yeah, that's a tricky one. It's possible to turn off the map labels, which would let you re-do it in a customized way on the map, and you'd just have to replace the contents of the table below.

It makes sense why he'd build it this way, but I definitely agree it'd be nice to be able to either feed it a list of names or like, have it spit out entirely empty places.

It looks like the code he's using is provided as part of a GNU general public license, so perhaps someone could make a new version that does have a feature like that (not me, as I already have too many coding projects on the go [he says, as he pins the code and looks at what it requires to tinker with]).
