Hello Mary,

I appreciate the fast response with the example code. Your
annotations solution ( looks pretty good. With minor
adjustments, I was able to add it to my code and also make it work for
the bottom text too. Thank you so much!

It'd be great if there was a newline character that didn't change the
justification. Thanks also for adding it to the enhancement wishlist!

Have a nice weekend,
