Hi there!
That’s a great question! This is absolutely doable–when performing a one-time import with iCal Importer, you’ll see options for “Import Status” and “Category” below the imported list of events once they’ve been processed. Simply select the events you’d like to bring in, choose the appropriate options for status and category below, and you’re good to go!

I hope that helps! Thanks, and let me know if you should have any other questions!
