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: [[32, -24, -39], [-49, 30], [32, -22, -10, 22, -15], [-28, -36], [-14, -4, 5, -21]]
Example Output: [-768, 30, 154880, 1008, 56]

Example Input: [[-39, -14, 23, -37, 41], [-24, 49, -29, 38], [-49, -46, -8, -28, 0], [40, -29, 11, 20], [6, 13, -41, -34], [-26, -42, 2, -2], [-22, -11, 24, -35, -36]]
Example Output: [-14, -912, 0, 800, -204, -4368, 19008]

Example Input: [[24, 4, -10], [-30, -20, -34, 1, 2], [-31, 40], [7, -26, 10]]
Example Output:
[-960, -40800, 40, -260]
