Delay (calendar) invitations, -requests/acceptances/declinations and more options for them?

I’m looking for a way to delay all outgoing messages, (calendar) invitations requests/acceptances/declinations included.

The Send Later addon does only work for regular emails.

All messages regarding invitations are still send out immediately!
Plus, Outlook has the possibility to edit my response before sending them, Thunderbird does not have any option here. You are only able to decide to send the message or not.

Those are quite vital features for me, since it happened many times to me that I used a wrong email address etc. and like it’s handled now, I have no chance to correct the error afterwards.
Cause all those messages are send out immediately.

Does anyone have a solution for this?
