Accepting an Appointment Into a Shared Calendar

I know you can do this for personal calendars...

Bug 6737 – Ability to Accept/Move an Appointment in another Calendar (as an invitee)

I cannot find a bug that says anything about the ability to accept an event invitation into a shared calendar that is mounted into my account. Anyone know what it is or if that bug exists?

Thanks,
Matt

Don't see one either - file it.
