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: [[9, 3], [46, 35, 15, 28], [47, 16], [22, 20, 4, 21, -3]]
Example Output: [0, 1288, 16, 1760]

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: [[-10, 39, -31, 2], [-45, 4, 34], [-19, 25, 47, -4], [15, -3], [-10, 18, 50, 30]]
Example Output:
[-20, 136, -4, 0, -270000]
