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: [[-37, -20, 18, -43, 7], [-49, -13, 11], [-29, -31], [-9, 6, -6], [3, 44, 33, -15, 20], [31, 20, 4, 49, -22]]
Example Output: [-360, 0, 0, -36, 880, -1760]

Example Input: [[47, 21], [-18, 34, -48], [15, 22, -30, 48, -13], [46, -31, 24, -10, -7]]
Example Output:
[0, 29376, -31680, -11040]
