I thought if I could utilise metadata to nest related content on a page it would save having to create many design customisations to achieve the same thing.
Any ways to achieve this? Hoping someone can help.
Have you tried nesting a Standard Page that has your globals keyword in it?
Yep, that's how I normally do it. Or you could try a declared var design area and print your keyword in there as %globals_asset_metadata_secondaryID^as_asset:asset_contents_raw%.
