How to treat multiple (the same) smart objects individually

I have a photo of some product cut out from a background. I turned it into a smart object and tuned with an adjustment layer. Later I made several copies of it, rescaled each of them and repositioned. Now I would like to edit each of them and change independently adjustment layer. The problem is, that PS treats them as a “clones” and every change applies globally to all these smart objects. Is there any way to do so other than rasterize these layers?
