? is there a way to mark all from pending to delivered/shipped

I dont know if this is possible, but I ran a special the last couple of days and have received more then 300 orders. Is there a way for me to change all of them at once from pending to delivered/shipped? :unsure:
Right now what I am doing is going one by one, which feel like it will take for ever.

Thanks in advanced.

Did you ever figure this out? I have the same question!
