Using elements on multiple pages

Hi,

Using elements more and more, I ran into the following configuration problem.

I use three elements: a layout element, a block-left sidebar element and block hook element that injects a header on a page. Each element is used on 19 pages. So every element contains a list of 19 pages in the 'display rules' tab.

The problem is this:
- Adding a page that needs these three elements requires editing all three elements. This is time consuming and error prone.
- The element configuration is hard to explain to editors of the website. This leads to questions and support.

The question:
- Is there a smarter way to achieve this? Can I wrap the elements into one super element? Should I leave elements and use templates?
