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: [[-17, 14, -8, -31, -2], [-9, 8, -31, -26, -40], [-3, 18, -35], [40, -23, -30, 28]]
Example Output: [224, 8320, 18, -33600]

Example Input: [[32, -19], [-27, 9, 45, 11], [-24, 21, -22, -16], [50, 7], [-31, 10], [24, 14, -29], [-39, 37, 16], [-5, -7]]
Example Output: [32, 0, -8448, 50, 10, 336, 16, 0]

Example Input: [[-49, 49, 4, -1, -13], [50, 27], [22, -7, 28, -48, -46], [49, -24, -18, 23, -44], [-47, 14], [11, -24], [-45, 49, 31, 5]]
Example Output:
[4, 50, 1360128, -19008, 14, -24, 0]
