Hello,

is there anyway to add liquid value on metafields with the new Shopify filter so we can filter by % discount on products?

i was looking for somehting automatic so when i change the price the filter update inmediatly and dont have to do it by myself in metafields.

Maybe adding some liquid in metafields but the discvery filter app doesnt regonize it.

{% assign discount_percent = product.compare_at_price | minus: product.price | times: 100 | divided_by: product.compare_at_price %}
{{ discount_percent }}
