Add more text in banner header Cascade

Hi all, can anyone give me a fix on this? On the Cascade banner header - I want to add more wording, in a different font size. Only options are Title and the wording on the CTA. I would like to add a sentence below the title. ANy great ideas? Or would I need to get someone to code it for me? Trying to get it to look like this example (hopefully this attaches ok)

Hey @fourtwentea,

Adding a feature like this would require assistance from a developer, however, this is an awesome way to use the banner, and we would recommend submitting a feature request. You can do so here

Have an awesome day!
