Hi Anthony

Thanks for your query and support.

You could perhaps try reaching out to the author and ask if they’d be willing to look into support for the SiteOrigin Editor Widget, part of the SiteOrigin Widgets Bundle. We’re always happy to help with those sorts of requests. I don’t see a setting in the plugin’s screenshots that looks related. Some plugins like Advanced Editor Tools have settings that help in that regard. For now, unfortunately, you’d have to build your shortcode elsewhere and then move it into the Editor Widget or similar. Sorry, I don’t have a solution to offer.
