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: [[-49, -13, 16, -46, -12], [50, 8, 14], [-36, 30], [-35, -39, 43], [-28, 27, -18]]
Example Output: [8832, 5600, -1080, 0, 504]

Example Input: [[-2, 16, -17], [34, -41, 9, 38], [-14, 13, -40, -3]]
Example Output: [-32, 1292, 560]

Example Input: [[41, 2, -37], [-9, 6, 29, 0, 41], [12, -47, 48, 2], [-1, 22], [-20, -50, 24], [7, -22, 29, -45, -48], [-8, 11, 21], [34, 16]]
Example Output:
[2, 0, 1152, 22, 24000, 1056, -8, 544]
