Hello wtraster,
Thank you for your question on setting a border for a section without having to change the color.
Currently, there is not an option to keep the same color as the rest of the page and have the section outlined with a border.
I would recommend submitting that idea for a future release. It may already be on the developer’s list of things to add, but it never hurts to submit it, just in case.
You can submit it by visiting our feedback page.
Kindest Regards,
Scott M
