Allow user to rename booked appointments

[malini]

Is your feature request related to a problem? Please describe.
Meetings are automatically named " and ". It would be nice to have this be customizable, or at least we should be able to rename it. Furthermore, if you go to your calendar to rename it, the new name does not get picked up in the bookings view. It keeps the original name

Describe the solution you'd like
I should be able to rename any meetings I have from the bookings page
