If you have 4 products: A,B,C, D, and want each of these products to be a cross sell of each other, you can accomplish this with our "link & save" feature. What this means is that if you select Product A and add B, C, and D as its cross sells, and then choose "Link & Save" the end result will be this:
Product A's cross sells: B,C,D
Product B's cross sells: A,C,D
Product C's cross sells: B,A,D
Product D's cross sells: B,C,A
This is very useful for say, linking cross sells that you know go great together (e.g. complete the look)
NOTE:
1) if you've previously saved the cross sells for Product A, then you'll need to change something about the cross sell to activate "link and save" (e.g. change the position/order of the cross sells, add/delete a cross sell)
2) when using "link and save", the cross sells for the "linked products" will be overwritten
