Yep, definitely using the same software, just a different theme :-)
You can add a new event and then drag it to the right to make it a sub-event but if you're finding that a bit fiddly, try this:
1. Delete the repeat in your example.
2. Select the for loop.
3. Press B to add a blank sub-event.
4. Double-click the sub-event and add a repeat.
Hope that helps! :-)
