Is this a good way to use CBT?

In this other thread I profiled an issue where we choose a style variation, make custom changes, select another style variation to see how it compares, and it looks like we’ve lost customizations.

To avoid this, I’m thinking it might be good practice to use CBT to export and import the current styling as a variation before selecting another for any reason, then we can easily go back to it.

Is this a recommended workflow for CBT, or is there another way to approach this with or without CBT?

Thanks!
