Allow option to add secondary conditional logic phrases, attached by AND/OR
example:
"SHOW this field if ANY of the following match:
-Product 1 IS t-shirt
-Product 2 IS t-shirt
-Product 3 IS t-shirt
...AND...
ALL of the following match:
-Product 1 IS NOT shoes
-Product 2 IS NOT shoes
-Product 3 IS NOT shoes
That way, this particular field would show as long as any of the three products selected are a t-shirt, and none of them are shoes.
This allows us to avoid having to make multiple versions of a field, and create the hide/show conditional logic for every possible combination.
