I would like to be able to copy a field from a metaobject (that is referenced in my products via a metafield), to product tags. I found the "Copy product metafields to each product's tags" task, but unfortunately it lacks support for metaobject_reference fields. I tried to implement this feature myself, but my skills are still quite limited when it comes to Shopify development.

To give more details about my specific problem, I have a Metaobject named "Book Author", and a corresponding product metafield with the type "list.metaobject_reference" (to allow multiple authors to be selected). I unfortunately was unaware that Shopify does not index metafields in their search results, but I have already added well over 3000 products using this field.

If anyone is able to help me in anyway, I would greatly appreciate it!
