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.

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

Example Input: [[15, 45, -1, 13, -15], [50, 29], [19, 40]]
Example Output: [0, 50, 40]

Example Input: [[18, 35, 15, -13, -22], [-23, 2], [-15, -37], [17, -37, 43, 12], [47, -3, 28], [41, 10, 27, -20], [21, 8, -31, -1], [-14, -49, -30, 16], [-12, -50], [-42, 1, 27], [-10, 39, -38]]
Example Output:
[-396, 2, 0, 12, 28, -200, 8, 6720, 600, -42, 380]
