Coming from MS Outlook, I used to be able to code the status of calendar entries as "Busy," "Free," "Tentative," and "Out of Office." It seems iCal only has Busy and Free. At the very least, is there a way to add Tentative to the list if not Out of Office as well? Since I use iCal for my business I have tons of meetings which are constantly being added, then moved and sometimes dropped. I'd really like to be able to put things as tentative.
