Allow "Sales" on a bulk amount of products at once

Currently it looks like Sales only allow you to mark a single product or your whole store. This isn’t ideal for storefronts that have multiple “lines“ of avatars and clothing, and want to promote just one of them. In this case it seems you either have to create a separate sale for every single item (which quickly becomes unmanageable), or you have to just discount your entire store just to discount one set. This is made worse when you’re trying to do a deeper discount on an older item and don’t want to discount newer items at all. Currently opting to just use discount codes instead, but that’s obviously much less accessible.

I think a very reasonable solution would be a way to just mark multiple products at once for a sale, or even just exclude products from the whole store sale option. Allowing specific adjustments to individual products might be useful as well. For example having a sale that is 50% off at base, but setting one product to be 45% instead, etc. I imagine the UI for this being fairly similar to how affiliate discounts are configured.

Thanks!
