Setup Info: I have a product with multiple attributes: Color, Size, and Package. The "Package" attribute has two values: Single, and Pair.

I would like to group in the pivot view, first by product and then by the "Package" attribute type/value (not variant).

Currently I can group like this (Product > Product Variant):

• Product A
• • Product A: Variant 1 (Color: Red, Size: SM, Package: Single)
  • Product A: Variant 2 (Color: Red, Size: LG, Package: Single)
  • Product A: Variant 3 (Color: Red, Size: SM, Package: Pair)
  • Product A: Variant 4 (Color: Red, Size: LG, Package: Pair)
  • Product A: Variant 5 (Color: Blue, Size: SM, Package: Single)
  • And so on...
• Product B:
• • Similar to above...

What I want is to group like this (Product > "Package" Attribute):

• Product A
• • Product A: Package: Single
  • Product A: Package: Pair
• Product B:
• • Product B: Package: Single
  • Product B: Package: Pair

I understand some products might not have the "Package" attribute. In those cases, I would like to just not show anything.
