Power BI desktop create a Calculated Row in Matrix Visualisation

[Anonymous]

Hello, I am brand new to PowerBI and trying to get my head around it.

I have a dataset with numerous columns like Product, Market etc, but the ones of interest are: Date (having as entries all the dates), Measures (with 6 unique entries e.g. Value, Litres, Units) and Value of measure (having as entries the value of each measure). A sample of the dataset looks like this:

At the moment I have created a matrix visualisation using these 3 columns that looks like this: 

  * for the purpose of sharing the photo I have removed the entries in the rows

I want to add 2 rows below these, that will be calculated from the previous rows of the matrix, Measure1: Value/ Units and Measure2: Value/Litres but I want these to be dynamic, so when someone drills down the report these will be adjusted.

It's something that is done so easily in excel and I find it furstating that I cannot find a way to do it in PowerBI. Is there anyone that can help me out?
