Mass price change not group pricing

[darktowerhobbies]

Ok what I need i think should be easy but I am missing it somewhere.

I have approx 150 books that need a price change they are going to go up I really don't wish to do them individually is there a way to change the price.

They are in the same group but in the pricing manager it only lets me change 1 at a time, and I would like to do all at once.
