stop reminders from waking up device screen?

[Guest DxTania]

whenever a reminder goes off on my omnia, the screen wakes up, and this is a hassle since it's usually in my pocket, and if i don't have time to get to my pocket my device screen will remain on until i finally click dismiss.

is there a cab file or reg edit so that reminders are like text messages, and only the sound is played and the screen reminder when i unlock my phone?

thanks,
