How to make a variant study?

Hi, I don't know if anyone knows, I don't. How do you make a variant study. So that the engine, livebook, etc agrees with the variant. Please help, thx :)

You create a study and change the variant to whatever you want instead of standard.

@LiamPutnam2008 Make a new study, when it goes into the "new chapter" section, click on the FEN. Go to the button under "variants" and choose your variant.
