I think that would not be possible. However, when scrolling through the list of Liquid objects (https://help.shopify.com/en/themes/liquid/objects) I saw something that could help: the metafield object!
The metafields object allows you to store additional information for products, collections, customers, orders, blogs, pages and your shop. You can output metafields on your storefront using Liquid.
