How to add text/image boxes in chronological order?

It's easy to add new text/images to the bottom of a page. But since I want the newest information at the top of the page, is there a way to add it such that all previous boxes are pushed down? So far, after each new addition, I have to manually drag all prior boxes down.

Second, if this is not the correct forum to ask such a question, my apologies. Is there an alternate forum?

Thank you.
