Enter calculated rows in visual Matrix

Hi, Syndicate_Admin 

According to your description, you want to add a row above your visual, and then you need to ask for the difference and additive, for your needs, first you want to add a custom row on your visual, then you need to add the corresponding row in your table to display the row you defined in your visual.
Second, if you interpolate and accumulate every two lines, you also need to be able to determine the line numbers for each row or your own classification settings, which is very complex and difficult to implement in Power BI.

Thank you for your time and sharing, and thank you for your support and understanding of PowerBI! 

Best Regards,

Aniya Zhang
