Request for changes for product merchandising for lamps and lamp shades

[Annyway]

I would like to exclude all of the "Tripod Lamps" from the purchase options when customers click on my lamp or lamp shade designs. Currently the available "sell this item on" options are: All options, Table sized only, Pendant sized only, This exact model only. The "Table sized only" choice only removes the pendant lamp from the customer purchasing options. When I select "This exact model only" I can publish the "Table Lamp" and the "Lamp Shade (Only)" each separately; however the customer can no longer change the shade material type or trim color and they're stuck with whichever ones I happened to pick. I'd love for the trim color to still be a choice for the customer somehow even when selling only one type of lamp separately. Thanks for considering! 🙂
