Sender address for appointments

Hi everybody,

just a quick question. Is it possible to configure different sender accounts/adresses when using multiple calendars in Kontact/KOrganizer?
Here is a quick expample:
If I have MailAcc1 and MailAcc2, and also Calendar1 and Calendar2, I would like to use MailAcc1 for Calendar1 and MailAcc2 for Calendar2 when sending appointments to other people. At the moment KOrganizer seems to use the default mail account only.

Thanks in advance.

Greetings
Marc
