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: [[44, 11, -29, -18], [4, 9, 48], [-31, -30, -29, 34], [-26, 24, 22, 34], [22, 38, 1, 17, -50], [27, -46, -25], [-1, 15, -40]]
Example Output: [-792, 192, -1020, -466752, -41800, -46, -40]

Example Input: [[12, 46, 0, -40], [47, 35, -29], [-20, 10, -6], [-49, -35, 29, 43]]
Example Output:
[0, 0, 1200, 0]
