Help! I have a zire 31. I need to customize my calender so that the schedule isn't on the hour (i.e., 8-9, 9-10 etc.) I want to be able to set a default background calender to read 8:00 - 9:15, 9:15 to 10:30, etc. I know I can change this on an invividual appointment through the details page and then the time tag. What I want to do is to change the default mode on all the days to an hour and fifteen minute interval. Any ideas? Any add ons that will do this?
