Feature description

Currently it's only possible to specify minutes/hours/days (when entering a custom value) before event start for reminders.
While this works it would be more handy if I could specify an exact date and time for a notification instead.

Why do you want this feature?

As usually I prefer to have a notifaction say one or two days before an event at a specific time I currently have to calculate hours manually for when to set the notification.
