Using Tokens to generate meta tags for taxonomy pages

I run CinemaFunk. I use taxonomy vocab and terms in a variety of ways such as tags, to categorize actors, actress, directors, films, and general tagging. For every term that has been entered and future terms, Nodewords automatically adds the default meta tags, especially the meta description. Not a problem.

I want to see if there is a way to add tokens to the nodewords default other pages to help generate original meta descriptions and possibly keywords for particular vocabulary and terms. I don't want 30 terms all to have the same meta description. I think it would be very beneficial if I could add tokens to automatically generate these two meta tags.

I've been able to create default tags for other pages using Nodewords, if I can just add tokens, I don't have to go through each term and write the meta description.

If anyone has any ideas or knows of a way to implement this that would be great.

Thanks,
Aaron
