Hi, larathomason. Great question!
We definitely feel your pain here, and do have responsive behaviors in the works for an upcoming release in the not too distant future. For now, though, I unfortunately don’t have any suggestions how you could customize your site to change per device.
If you need an immediate solution, your best bet would be to hire a third-party developer who could take a look. Should you be interested, we’d be happy to provide you with a list.
Sorry I don’t have a better answer for you, but please rest assured that help is on the way!
