Hello, i think this would be a Big Feature

I think something like:

!rendezvous eventname eventdate

is quickly needed (at first)

The four commmands to combine are the following:

!cal edit

!event create toto

!event start 2021/02/21-13:00:00

!event confirm

Calendar creation is now much closer to "one line" and can be achieved in 2 commands:
/calendar create [name] (description) (timezone) (host)
/calendar confirm

I chose to keep the calendar confirm flow so that there's still a change to correct any typos and look things over before its created.
