itch.io

It's the first time in three years that anyone asks for it, so I don't think it's a big issue with the vast majority of the players. It's not super complex, though, so with very little practice in Renpy you can make yourself a patch that will overwrite the scenes ("Labels" in Renpy) you wish with your own text. 

If I see more demand I'll consider adding it, but don't hold your breath.
