We’re using the Empire theme (but this is also something we’d like to do on Dawn)
In the theme editor, if you add a Section of Text With Image then when you cilck to add a dynamic source (Image or text) you only see Brand Image metafields (logo etc..) or brand text (Strapline) as dynamic sources that you can pull in there.
We would like to make those source selectors show some custom metafields we have set up… anyone have any idea how to do this? (Shopify and the Theme developers, Pixel Union) have pointed me to the Shopify article on mapping metafields, but it does not cover this requirement.
