Thanks everyone for chiming in but I specifically was talking to the Moz Pro crawl and results here in Moz Pro. I thought that was implied by asking it on this forum.
The suggestion to 'Add a meta robots noindex tag to each of the pages you want removed from the index' is quite impossible as there are over 10000 pages (some outside our CMS footprint, but on our domain). I wish it were as easy as adding a single line to a header include!
