Can I hide photostreams that have been shared with me without unsubscribing?

I would like to be able to view the pictures on my Ipad, however I don't want to have them on my macbook air. I don't want to hide photostreams that I have created, just some of the ones that have been shared with me.

I don't think it can be done, but if someone knows how I would absoltuely love to know how!
