Hi and thank you to use our application.
Your request is a good idea but difficult because we must manage all events in this case (as rechedule, cancel, approve, deny,…).
In some days we publish a new release of (e)help, it doesn't contain your request but we see if we can develop it in a next release.
If someone have a library to manage a calendar entry from an other database that can help us.
Thank you and enjoy to use (e)help.
