Include select items from a Collection List

My client would like to have a “library” of pieces of content (rich text) that they could pull into multiple pages. Basically, I’m writing a bunch of short pieces of copy that they want to mix and match on a set of “Solutions” pages. But, they want the content in those blocks to change everywhere when it is edited.

It would work like this:

  • Page A: Item C, Item F, Item G, Item L
  • Page B: Item A, Item F, Item L
  • Page C: Item B, Item D, Item G

I thought creating all of these bits of copy in a collection would be the best way. However, I don’t see how I can easily pick and choose the items from the collection that will appear on the page. I see filtering but that doesn’t quite fit the bill as far as I can tell.

Maybe there’s a better way to do this entirely?
