Thunderbird calendar edit multiple appointments (e.g. categories)

[Hugole1]

Please add the possibility to edit multiple appointments.

I have created about 20 appointments. Now I want to add the same category to all these events. I also want to change the reminder time for all these appointments. Currently this does not seem to be possible.

Yes, me too! I decided that instead of having five different calendars, I want them to be in a single calendar, differentiated by categories. However, those calendars contain hundreds of events, and I really don't want to edit each of those manually.

After right-clicking one or more events, there should be a few options such as "Move to ..." and "Change category to ..." to allow me to move tasks to a different calendar and change the category.
