Customizable Average Calculation

I have a graph that calculates the hours of different job types. Since DOMO has a label feature for %_PERCENT_OF_CATEGORY, it would be helpful if DOMO could add in the grid line settings an option to allow users to choose different options for calculating the average. In this example we are calculating the average value in hours, but it would be very helpful to have an additional feature to calculate the hours in percentage of each type of job.
