In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.

[[-33, 35, -21, -2], [34, 49], [-45, -20], [-26, -48, -23, -12, -46]]
[-2, 34, -20, 688896]

[[0, -44, -42], [-1, -2], [-40, 23, 19, -23]]
[0, -2, -40]
