Notification center customisation

Apologies if this has cropped up elsewhere - I had a bit of a search but didn't see anything.

Obviously there are probably several different combinations of reminders / calenders etc to suit different people, but I'm finding reminders quite handy to put in, and then pull down the notification center as a quick and easy to see what's coming up that might need attention.

However, as far as I can tell, its only showing reminders if they are due within 24 hours. It would be useful to view all upcoming reminders, even if they weren't due in the next 24 hours.

Has anyone figured out if that's possible?

Thanks.
