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: [[4, 48, 11, -29, -42], [2, -23, -18], [-7, -27], [-43, -18, -34, 16]]
Example Output: [-8064, -36, 0, 9792]

Example Input: [[-11, 26, -48, -18, -14], [-32, 10, -27, 15, -1], [-10, 9, 33, -46], [-4, 1, 40]]
Example Output: [-314496, -320, 460, -160]

Example Input: [[49, 40, -49, -17], [-20, -3], [39, -42, -44, -6, -15], [-47, 47, 17, -34, 43], [-36, 44, 4, -1], [4, 4]]
Example Output:
[40, -20, -11088, -34, -6336, 16]
