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.

[[-19, -33, -24], [-1, 49, -19, -37], [-5, -49], [-2, 3, -48, -42]]
[-24, 0, 0, -4032]
