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: [[-13, -32, -13, -37, -50], [-7, 40], [10, 2, 17, -40], [-17, 36], [29, -8], [-10, 30, 34, 39]]
Example Output: [1600, 40, -800, 36, -8, -10200]

Example Input: [[32, -48, -17], [-22, 28], [11, 2]]
Example Output: [-1536, -616, 2]

Example Input: [[5, -3, -12, -15, 49], [4, -14], [-13, -11], [3, 47, -12], [30, -42, -30], [-29, 16, 34, -47], [-24, -32], [31, 24, -34], [40, -45, 3, 21]]
Example Output:
[-12, -56, 0, -12, 37800, 544, 768, -816, 40]
