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: [[-8, 23, 0, 29], [-9, 19, -40, 19], [31, -35, 17], [18, 30, 38], [7, -48, -19], [-14, 39], [-21, -2, -15, 7]]
Example Output: [0, -40, 0, 20520, -48, -14, -2]

Example Input: [[20, -49], [24, -16, -38, 50], [-40, 37, -13], [-21, 45], [-17, 17, -5], [-2, 47, -16, -2, -17], [22, 37, -27, -31, 44], [-8, 28, 44, 21, 37]]
Example Output: [20, 729600, -40, 0, 0, -64, 968, -9856]

Example Input: [[-31, -3], [23, -33], [-15, 45, 17], [26, -43, 31, -20], [-31, 29, -50, -45], [44, 20]]
Example Output:
[0, 0, 0, -520, -50, 880]
