Pivot Rows on Matrix Visualization Month + 1

[andyor]

I have a dataset in the following format. Notice InitialDate of July 2022 has 1 corresponding row of RollingDate and Churn, June 2022 has 2 corresponding rows, May has 3 etc etc

And I want to display the results in a matrix like this. 

The problem I'm finding it that if I just use the RollingDate as Columns and Churn as the Values, it looks like this

But what I want is this

Any help greatly appreciated

First, add a Rank column to your table as follows:

Rank = 
VAR __InitialDate = 'Table4'[InitialDate]
RETURN
RANKX(
    FILTER( Table4 , Table4[InitialDate]  = __InitialDate ),
    Table4[RollingDate],
    ,ASC
)-1

Visualize on a Matrix visual as follows

Thanks @Fowmy 

I got on the right track with a much more crude solution than yours but got stuck again. 

How does one switch true() for comparing month + 1, month + 2 etc?

Finally, how can I display 'Original' in Rows to the right of Initial Date?

If I just add to Rows they automatically go into a dropdown... Thanks in advance. Subbed your youtube and look forward to going through your videos!!
