Create a "reusable" block

[budparr]

As discussed. I created a block on the main about pages and I'd like for the client to be able to use that block on interior about pages without having to duplicate the block's content.

I don't really have a straight forward solution for this. Anything we try would be complicated to explain. The Joinproviders solution is a bit complex for this unique use case (knowing we'd have to let carl maintain it etc...) I thought about a way to use a block from the parent, but we don't have any identifier set on those blocks.

What we could do is simply have this block hardcoded somewhere, and they can just choose to use it on a page, and select its position.
