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: [[-31, 42, -40, 28, -21], [-41, -14, -19], [-6, 34, 43, 38, 36]]
Example Output: [-47040, -14, -279072]

Example Input: [[-16, 2, -49, -3, 6], [-20, 3], [38, 15, -34, 27, 37], [23, -3, -3], [-46, -36, -36], [49, -45, 38, 37, -35], [38, 21, -4], [3, -38], [28, 37, 45], [0, 5], [6, 42, -24], [48, -45]]
Example Output: [-192, -20, -1292, 0, -59616, 38, -152, -38, 28, 0, -6048, 48]

Example Input: [[50, 40, -21, -29], [16, -29, -17, -2, -24], [-38, -1, -38, -50], [47, -22, 9, 10, 3], [-39, -16, -9, -47], [20, -7]]
Example Output:
[2000, 768, -72200, -220, -16, 20]
