Stock Alarm Snooze help


Android Enthusiast
I get many alarms and reminders that I want to snooze, but why can't I set snooze to a differing time than 15 minutes.
For example, I get a friends birthday notification 24 hours in advance, but I really want the reminder for the morning of the birthday, so to remind me to send a message!
Why is this such a difficult requirement that Google can't build in to their stock notification system?!??!
