Currently, you can pass in a list to matrix jobs. If more than one list is passed in, each option is run again each other option. Instead it would be great to have 1:1 mapping of lists. For example :

Days (List 1): [Monday, Tuesday, Wednesday]

Fruit (List 2) : [Apple, Banana, Pear]

Output1 : Monday, Apple

Output2: Tuesday, Banana

Output3: Wednesday, Pear
