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: [[21, -8, -12], [-17, -3, -44], [14, 31, 21], [-20, 17, -11, 23], [49, 47, -3, 41, 29], [-11, 0, -24, -36, 14], [18, -19, -15, 29, 48]]
Example Output: [96, -44, 14, -20, 0, 0, 864]

Example Input: [[-33, -7, 36], [-27, 20, -2, -2], [-7, -7], [7, -29], [-3, 0, 30, -28], [27, 30, -13, 42], [33, -10, 21]]
Example Output: [36, 80, 0, 0, 0, 1260, -10]

Example Input: [[-15, -43, -40, -37], [-46, 50, -2, -21, -7], [49, 3, -27, 25]]
Example Output:
[-40, 4600, 0]
