Make a Non-duration calender event?

Sometimes I want to add something to the calender to remind me to do something. I don't want it to be an event that is a certain length of time... just a reminder, then it's done when I click dismiss.

I know about the remember app but this only allows a certain day for a due date, not a specific time of day.

Any ideas? I prefer to stick with the stock BB10 apps over downloading different Calender apps.

Thanks
