Hi Doug,
Thank you for problem-solving with us and spending time to share with the community!
As Editor X evolves, we plan on creating more tools that would give our users control to create a unique design experience on their sites. This idea is not far from from that focus.
We agree this would be a very useful and powerful feature. We would need to investigate if it is possible to implement into our platform.
Currently, we do have the Corvid APIs which can override some style properties for elements, throw your own custom logic on top and you will have dynamic styling.
We hope to continue bringing to production more features that would give you more control over the design. We would love to hear more ideas from you or more on this in the future.
