You might be better off asking over on the Genesis community forum, I don’t think there are many Genesis users that visit here that can help you, which is likely why your question has gone unanswered for so long. I didn’t answer it sooner thinking maybe someone else would be able to help you.
To be honest I’m not familiar with it, but usually ACF requires modification of the theme files and what I think you’re looking for is the ability to modify those theme files through the Genesis admin panels.
