Oh, sorry, you fell victim to my morning grogginess - I reached for the keyboard right after being woken up.
So, there you will need either the Style Sheet Loader Extension plugin and have to create a stylesheet which you can load with the plugin, and probably there will also be a way doing it via scripting of Krita. But since I’m no coder, you have to do it yourself or hope for someone like our script wizard @AkiR who will help you with that.
