variable strings

Anyway to insert dynamic data as a variable string. For example, a placeholder $TEMP might point to a current temperature…or a stock number. I know I can do some of that with RSS but I don’t want to crawl on the screen. I’d like it static.

thanks for any advice.

This is not possible with the built in features. You could have someone (or us) create a custom layer for you that does that.
