Complex hyperlinks in a dynamic text box? (with Flash 8)

Is it possible to control aspects of a movie clip using hyperlinks within a dynamic text box?

I am using LoadVars to import text from an external .txt file into a dynamic text box, and although I can create simple hyperlinks (using <a> tags) within the box that can redirect the current page to a new URL, is it possible to have links which work within the flash movie - i.e. navigating to another scene?

Any help would be much apreciated! Thank you,
