Is it possible to display only discounted sizes in a Promo collection?

Hey!

I have a store where I sell shoes. Every pair has different sizes.

I have created a collection called “Promo” for discounted sizes.

Is possibile to ONLY show the discounted sizes in the Promo collection?

so if a product has 5 sizes but I wanna discount only 2 in the Promo collection I wanna see that shoes in only 2 sizes.

hey~ Has your issue been resolved?
