Windows 8 Calendar reminder time choices - what the heck?

[a_gunslinger]

Really like the W* phone over all. But for calendar one thing is maddening. For "Reminder" times for a calendar event your choices are nice increments until 1 hour, then it jumps to 18 hours. Wish I had some options between 1 and 18 hours!

Likewise, there' nothing between 1 week and 1 day! Anyone know a way to add increments/
