Creating products that have options (not a variant)

Question:
[I sell kitchen cabinets and have many cabinets and doors that have the same name, but have different sizes. For instance a ‘Hi-line Carcase’ comes in many different widths and all have different cost and selling prices. I do not want to have to create variants and have to modify each variant price, etc, it would take far too long.]

Product:
[Wix Studio Editor, Editor X.]

What are you trying to achieve:
[I would like the ability to create a product that can have options but each option points to another product, not a variant, in the same collection.]

What have you already tried:
[Editing the csv files to get the result.]

Additional information:
[None.]
