App to turn off reminders during work hours?

[jaundice]

Hi all,

I'm looking for an application which must exist but I'm having trouble finding. I have my Treo Pro synced with my work computer so it has my outlook calendar in it. The irritating thing is that while I'm at work I already get the outlook reminders, and don't need my treo beeping away all day. However, I do use outlook to set up personal appointments on nights and weekends and don't want to turn off reminders on the treo altogether.

Is there an app that will let me set hours within which I don't want to get reminders? I know I can turn off the sound but even just all the notifications and vibrating get annoying. Thanks!
