Saving settings for custom journal styles?

[red_eft]

Is there a way to save changes you've made to a style? I want to play around with the new styles, but I've made some changes to my current style. I'd like to have my current (edited) style as a back up in case I'm not satisfied with the new one.

I've poked around a bit, but couldn't find anything on this, so forgive me if I'm missing something obvious.
