CUSTOM DIALOGUE BOXES AND FONTS

Took me a while to figure out how to use Wolf RPG Editor. My only concerning issue is how to have custom boxes or fonts.

This is what I mean. As you can see, its a basic blue box. I want to chnage it to be something different.

And kinda like this, the text box from the Crooked Man, a game also made with Wolf RPG Editor. How would I go about changing the box? Do I have to make my own somehow?

Edit: After some tooling around, I was able to figure out how to change the choice box. But now I still need the dialogue and the menu box (like save game boxes and stuff)
