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, 31, 49], [7, -48], [-5, 16, 2, 28]]
Example Output: [2, -48, 896]

Example Input: [[-26, -47, 10, -26], [14, -47, -18, 12], [-33, -10], [-50, 23, -25, -48, 26], [4, 34, -30, 37, -23]]
Example Output: [6760, -3024, -10, 62400, -4080]

Example Input: [[-32, 1, -44, -6], [-14, 43], [16, -26, -26, 41, 30], [-8, 28], [-43, 42, -41, 20, 13]]
Example Output:
[-8448, -14, 324480, -224, 840]
