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: [[-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: [[33, 37], [34, 43, -49, 9], [27, 15], [46, 38, 47, 41], [-19, -37, 30, -18, 33], [-15, -14, 17]]
Example Output: [0, 34, 0, 1748, -540, -14]

Example Input: [[-21, -9, 40], [47, 31], [-9, -13, 16, -47, 41], [-33, 43], [49, 7, 16], [-16, 17], [-31, 25]]
Example Output:
[40, 0, 16, 0, 16, -16, 0]
