Action delays longer than 60 seconds?.

I would like to have delay actions of longer than 60 seconds (specifically, delaying the OnShow of a button.). I was told I could "stack" action delays, but this does not seem to work since I can't attach the action to the button itself, but must attach it to the page. The shortest Action delay fires first. I don't think there is a way to attach an action to another action, either. Is there a way to change the 60-second default time, or another way to prevent a button from displaying for longer than 1 minute?Thanks,Jessie
