@Shinooj It's not easy to add an extra "total" row to a matrix or table. You have 2 options. One, you use a disconnected table for your rows and then construct a measure that determines which row you are in and returns the appropriate calculation. Two, you create a measure for each row and use the "Show on rows" feature of the matrix. Sample data would help to be more specific in terms of the solution.

Sorry, having trouble following, can you post sample data as text and expected output?
