Align multiple graphics across the timeline

Hi

I have made some adjustments to my text formatet graphic elements, across the timeline (using text style, dragged over the clips).

But now i see the text located in the graphics elements have shifted as they have "justify left".
Now this can be justified center, but there is no way of making all the graphics elements aligned to the center all in once, meaning that i have to go to every graphic element and centering this.

There must be a smarter way, but how
