Thank you, Leo. I agree that steps 3 and 4 could be combined but I think my method is OK. Are you happy with the attached picture? If you are, then my method works. (It is possible that I haven’t described it accurately — it is very late here!).
Remember to drag the right-hand end of the long ties BACK to the end of bar 1 (not vice-versa).
Also, be careful in Step 1 to enter only quarter-notes! Those ties into bar 2 don’t exist until Step 3.
