I really want to get an answer to this question, even if in reality it's a No:
Is it possible to create a calendar view with two entries per item?
Unfortunately this question has been marked as answered, when neither the answers nor the eventual solution are directly relevant; mostly because the OP's actual requirement is only indirectly related.
I would like to edit the question to be something closer to the OP's actual requirement ("How do I overlay two calendars on a view?" or similar), and then re-ask the question without fear of it being closed as a duplicate.
Is this acceptable?
