Specify URL's In Site Optimizer

It would be great if I could specify URLs in the Sight Optimizer. For example, I have a photography business that has done thousands of posts from photo sessions, which have no real SEO value, just value to the clients and to my portfolio. So I don't what site optimizer to optimize a bunch of worthless pages. I want it to optimize specific pages and articles.

I don't want it to just blow through all my credits, hoping it might find a good page to optimize. Thanks for the help.
