I have a landing_page/page_builder content item with multiple zones and blocks.
In my migration I am creating other content items and using references to store the content_id.
So for injecting id's into a block that is a collection it uses name: locationlist, value: '1,2,3'
What I was hoping to do was 'name: locationlist, value: 'reference:page_1,reference:page_2,reference:page_3'
