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: [[-2, 41, -50, -30], [5, -47], [35, 6, -46, 21], [33, 23, -6, -26], [-46, -15, -2], [-16, 29], [-20, -12, -20, -50]]
Example Output: [-3000, 0, -276, 156, 92, -16, 240000]

Example Input: [[-1, 25, -35, -36], [-43, -30, -32], [-25, -19, -43, 10, -47], [-39, -12, 39], [18, 17, -2], [-48, -33, -14], [9, -29, -36, 31, -5], [44, 10, 49, 12]]
Example Output: [-36, 960, 10, -12, -36, 672, -36, 5280]

Example Input: [[38, 34, 13, 46, -30], [-48, -47, -50, -22], [-4, 21], [-29, 42, 35, -42], [21, 8, -25, -25], [-29, 12, 18, 50, -34]]
Example Output:
[-1782960, -52800, -4, -1764, 8, -367200]
