Manage all series

So I am trying to manage all of the series that I have set over the last few years.  I have recorded some that are all don and have run their course. I we to:

Contour

Saved

Scheduled

Series Priority

I can them all....all 62 of them. I want to delete all unnecessary. If I move down and hit the D button, I can delete it and Only 1 at a time. And then it starts me at the top again.  Ugh. This will take forever. Can I do this on line and select all I want to delete and the reprioritize the ones I want to keep?
