[FR] More snooze options

[Nitero]

When using the alarm reminder type there is only the option to snooze for 10 minutes (or anotehr fixed interval from the settings). It would be nice to be able to snooze for different durations. For example if I'm in a meeting I know I won't get to it in the next hour. TickTick does something like this with multiple predefined options, even including a "next day" one.
