Hi @aliceweegee ,
You can use the Easify Product Options app to integrate Lamp Shade products as custom options for your Lamp products. This way, you can conveniently handle them as distinct products with individual SKUs

Keep in mind that “Lamp” is one of the pre-designed templates available in the app. Simply choose it and customize the template according to your store’s needs. Easy as that!
