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: [[18, -11, -13], [-20, -21, 26], [40, 6, 3]]
Example Output: [18, -520, 240]

Example Input: [[-33, 49, 15, 3], [49, -36, -17], [-5, 18, -4], [39, -24, 1, 49, -14]]
Example Output: [0, -36, -72, 336]

Example Input: [[49, 11], [-46, -11, 7], [-43, 45, -35, -6, 48], [41, 8, -6], [-7, 14, 35, 6, 0], [-44, 40, 50], [-41, -5, -50, -47]]
Example Output:
[0, -46, -288, -48, 0, -88000, -50]
