Why is so hard for adobe to create a preview of your double-sided file before printing it?

When you have to print double-sided files it is complicated to imagine how you have to set up your file so that you can print it correctly. It will be much easier if Adobe has a preview so that you don't print things upside down or from right to the left instead of from the left to the right and waste a lot of paper and ink. The preview it currently has doesn't give that kind of information. It only displays what you can see in your artboard except that it's smaller.
