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: [[-10, -39, 40], [-5, 36, -28, 48], [5, -50, 31, 10, -16]]
Example Output: [-400, -48384, 8000]

Example Input: [[25, 34], [43, 2, 40, -25, -45], [16, -49, 40, 18]]
Example Output: [34, 80, 11520]

Example Input: [[-36, 18, 40], [-32, -18, 0], [21, -23], [-8, 49, -14]]
Example Output:
[-25920, 0, 0, 112]
