Doe anybody know a way to get Outlook to automatically turn on Out of Office Assistant?

I keep forgetting to turn the feature on and it's rather annoying.

I imagine I'll have to have Outlook running but a way to get Outlook to turn on Out of Office Assistant some time in the afternoon before I'm actually away would be very helpful. (Yes I know I could set a reminder but I thought you people may have a super cool way of doing this)

Thanks for any comments
