Well, there are functions under Settings for exporting all of your presets or importing all of your presets, but importing presets using that function won't overwrite your current presets which bothers some people b/c you end up with duplicates. Since you're importing them onto your computer, you could just delete the directory holding your user presets, and then importing wouldn't lead you to end up with a bunch of duplicates. But keeping your presets in a single preset list might actually be an easier way to go about things if that works for you.
