Ragic CROSS JOIN

I think many wondered how to make a complete list / price list of products based on product options.
Product1 (Opt1:1,2; Opt2:A,B)
Price List:
Product1,1,A
Product1,2,A
Product1,1,B
Product1,2,B
I think many of us use to create a price list excel power query:

My question is, is there a way to make cross join tables/ sub-tables or dropdowns?
