How to noindex old and future (media) attachment pages?

Hello,

– What is the best and fastest way to noindex already (Google) indexed media attachment pages? I know i can do this manually in the Yoast plugin at each page and recrawl my website, but its a lot of work because there are many. Is there a faster way?

– And what is the best way to stop (media) attachment pages from indexing in the future? I read excluding the (media) attachment sitemap. But what about toggling the ‘Media’ meta robots (under titles & meta’s/post types) to noindex. Is that also a possibility? And if so, should i change the title template? Or should i do both?

I was in this conversation with a Yoast plugin contributor, but she suddenly stopped replying, so my question isnt fully answered, yet.
