Combine Theme Styles

I have a few theme styles in a site from pasting and using different templates to produce the content. 3 theme styles have been set up in the dropdown.

If there are 1+ theme styles in the drop down how do you combine those classes so you only have one theme style and therefore don’t have to use more than one condition?

How would I see which classes are in each theme style aside form exporting them individually?

I’m new to the builder and maybe there is a place to manage this. I have tried the class managers in bricks and advanced themer, but it doesn’t seem to tell you what theme style the class is associated to.

Global classes aren’t associated to the theme styles. The global classes are available independently of the theme style you apply.
