You can do both things from the Local Profiles page in vorpX Config app. You’ll see the corresponding buttons when you select any profile.
Easier still, you can drag and drop profiles listed there one at a time into a backup folder. Then should you want to import one again later, simply drag it from your backup folder into the app list.
It’s a good idea to make backups before a new vorpX update. Sometimes a required reinstall can default your entire list. Or at least it used to.
