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: [[-15, 21, -15, -36, 14], [-48, 29, 33, 14, -17], [-30, 39, -24, -2, 46]]
Example Output: [-504, -672, -66240]

Example Input: [[-36, -23, -48, -14, -27], [-26, 28], [-29, -37, -50, 31], [-11, 46], [8, -7, -16, 42], [43, -47, 8, 3], [0, 36, -48, 44, 49], [43, 31], [-12, -17], [47, 10, -48, 43]]
Example Output: [-24192, -728, -50, 46, -5376, 8, 0, 0, -12, -480]

Example Input: [[41, -18, -21, 50], [-5, 43, 30], [2, -9, 24, 31, 14], [-10, 33, -30], [-15, 31, -43, -48, -23], [2, 28, -2, 15], [-12, -38]]
Example Output:
[-900, 30, 672, 300, -48, -112, 456]
