A mod/editor that allows you to add skills from other classes

When Grim Dawn Trained Hard released, it was the best thing as it allowed you to add skills from other classes to your build. I haven’t found a mod or editor that lets you do this. The save editor only lets you edit the skill points you have, not add new ones and there’s no trainer that does this as well. Is there ever going to be something that has this functionality?

[Tool] GD Defiler

You select mastery, select your skills in-game. Then it’s best to exit the game
(although Main Menu, selecting different character and Alt + Tab should be fine)

and after that you can choose to reset your mastery (and increase skill levels) in this program
and have the option to leave the skills from the mastery you reset.

Thanks for the reply, I think that is what I’m looking for.
