Text Box Gadget Formatting

Is there any way to do more formatting on these text boxes?

Here is what I have:

I want to center the text under the Group Header but I’ve already got it right-justified. I can’t just move the gadget to the right because of the border and the background color, which it appears I’m unable to change, is white compared to the Group Header background.

Any thoughts guys or am I stuck?

Thanks,

Dave
