Send email when appointment cancelled on shared calendar

[bhilgenkamp]

I am planning on having a single calendar that will be shared to multiple people with Manager rights (users need to add/remove/modify appointments). Is it possible to either send an email when a appointment has been deleted, or some other way to leave an audit trail for appointment deletions? Our current calendar system has this and it has saved us a couple of times due to accidental deletions, hoping Zimbra can do the same.
