Meta Keywords in Panel Pages

I really think this is a wonderful module, and it will certainly be helpful with my search engine marketing!

I was able to figure out how to assign site and node keywords, but all my site pages are panel pages with the nodes forming the building blocks. I was hoping there'd be a way to assign meta keywords directly to panel pages using the SEO tools suite. Am I just missing that, or do I need a different module?

Thank you.
