If it is just the font, font style and font color, for example, you make a new Style out of the text, name it, and then use that to change all of the other titles. Select the text and click on the style. From the menu choose "Apply Style with Font Size"
The shape of the text box can't be automated as far as I know. (Apparently you can - Ann is correct as usual - create a template.)
Just FYI, attributes are things that apply to clips, not synthetic media like titles.
