[Missing Feature] Default Calendar app does not allow editing a single event in a series

• /e/ version: v3.0.4
• Device model(s): FP5

Summary

In the Calendar app, add the option to edit only a single occurrence of an event in an event series.

Description

What is the current behavior?

An event series is created in the Calendar app (i.e. recurring event). When I hit 'edit' on an event in the series, I am given two options: 'change all events in the series' and 'change this and all future events'.

What is the improved behavior?

When I hit edit on an event in a series, I should have 3 options: the two previous and 'change only this event'.

What does it bring?

It is a standard feature on existing default Android calendars, and should be on e/OS's.

Mock-ups

As the existing Android does it.

Examples

Users will be able to edit a single event in a series, such as a different location for a recurring sports event.

Validation

When a user tries to edit an event in a series, 3 options should appear in the popup. If 'only this event' is the selected option, when the user is done changing details, only that specific event in the series should have any changes.
