Hi! I'm hoping that I'm just missing it, but is there a way to integrate another tinyMCE field?

I've gotten a hang of it, but I can't figure out how to create a custom section where a user can either

A. add images (like a small gallery) or

B. embed a gallery like FooGallery

The HTML field is not a field that can be edited by the user, but users can't embed or add any coding in the textarea fields.

Thanks!
