Metafields Guru

Extremely powerful app that really allows you to add as many custom fields of data as you need.

The fields are exposed in the Shopify API via connections such as Celigo, making it very easy to sync data between ERPs and Shopify.

Reaching out to support was easy, helpful, and a great experience.

I would highly suggest you looking at this program if you need more power with Metafieds and Shopify!
