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, 2, 10], [-8, 18, -35], [0, 21, -23, -40], [10, 27]]
Example Output: [20, -144, 0, 10]

Example Input: [[1, 46, -20], [36, -9, 24, 43, -5], [-45, 7], [29, -3, -23, 47, 23], [-12, -6], [40, -32, 4], [-17, -30, 13, 9]]
Example Output: [-920, 864, 0, 0, 72, -5120, -30]

Example Input: [[17, 8], [30, 17, 16, 12, -11], [1, 16, 48, 45], [38, 1, 2, 46]]
Example Output:
[8, 5760, 768, 3496]
