i have both plugins WPC Grouped Product with WPC Linked Variation. i use the linked variations to link between different colors  of products (Womans bra or leggings) and i use the WPC Grouped Product to create sets of bra and legging. 

how can I integrate the different colors into the sets? so the customer can select in the grouped product different colors for each part or for the set?

how does the integration between WPC Grouped Product with WPC Linked Variation works?
