Mass scheduling of tasks.

Looked around for a while and couldn't find an answer for this one:

I have about 200 tasks in a single group in my Scheduled Tasks tab. Each task is associated with its own query for specific computers. I need to get all 200 of these scheduled to run once per week at a specific time of day.

Is there a faster way to schedule them all at once with the same schedule than going to the properties of each one by hand and scheduling them one-by-one?

Thanks!
