Hi there!
We've shipped a new small feature which allows you to change the name of an adhoc session event.
To get started, enable the Change name of adhoc session on your desired roles.
Within the Sessions, users can click the pencil icon to edit the name of the session.
Developers
This new feature relies on the sessions:edit_adhoc_name permission.
When retrieving session events, if the name_override property is set, this should be used instead of schedule.name
