Hi, Gary. I'm not sure about the built in part of your question as I think there are still a few things left for approval for this functionality to be part of core (at least according to the ongoing discussion logged in the tracker here).
However, I can report that I have had pretty good success myself with using Piers Harding's tool as of 2.3.2 for adding courses, at least, and he has posted a link to the latest version at the bottom of the tracker thread.
I know you are on 2.3.3, so I hope this still helps you seek what you need from the right folks in the right places. We haven't done the bump to the latest 2.3 version yet, so I can't confirm whether that will matter or not. I'm hoping not, but even if it does, Piers has been extremely fast in responding to community requests in the past.
Best,
Lesli
