MarketPress Product No-Index Settings. Don't want products indexed in google.

Hello

Is there a way to make all the products in marketpress No-Index? I do not have the time to set SEO for every single one. (Over 150 products) . I am worried that this is actually causing a negative SEO effect on my site as all of these are indexed in google and get no backlinks, social signals, etc. I focus all my SEO on store pages and posts. Please let me know how to set these for No index.

Thanks
