It's easy, easy, easy to make a schematic symbol. Open the library editor from the schematic screen (it's on the top button bar), add the pins with names and numbers, draw a rectangle for the shape and you're (mostly) done. There are a few details regarding things like power pins but the help files cover this very well. Save your personal symbols in your own library so that future updates to the base libraries don't overwrite yours. One possible gotcha is that you'll need to remember to add your library to new projects and save the project options. It's just a couple of clicks but if you forget to do that, you'll wonder where your new parts went to.
