Scenario / use-case:
I've accepted a meeting invitation (A) and intend to attend.
I've been invited to another meeting (B) at the same time that I need to attend.
I'd like to let the meeting moderator of meeting A that I won't attend or will be late and want to leave it on my calendar in case meeting B is cancelled or rescheduled.
In Verse (and Notes) today - I can't change the "state" of a meeting from "Accepted" to "Tentatively Accepted"
In Notes I can edit the entry to check the box "Show as available" but this is really obscure.
In Verse (and Notes today - I can go in the other direction, I can change the "state" from "Tentatively Accepted" to "Accepted"
Add the "Tentative Accept" action to accepted meetings.
