When editing a calendar, please allow us to select what calendar the edits go on when making the edit.
This allows us to have full autonomy and ensures we have selected the correct calendar, and if we haven't, then we can easily fix it without having to recreate the entire event.
Example: I forgot to change the calendar to the desired calendar and my edit went to the "All Events" Calendar as a default. However, there is no way to correct this without recreating the event.
