How to Display Multiple Rows in a Single Cell of a Matrix or a Table

How can I condense multiple rows into a single cell in a Matrix or a Table?

Obviously, it is easy to display all details like you see below:

But what if for every product I just want to know what countries it is selling in and what channels are used? Like how it is displayed below:

Turns out we have to write a bit of DAX but thankfully, not much at all.

You can get the detailed explanation from my video but here are the DAX calculations that I had to create to enable this use-case.

Product Channels = 
IF(
    HASONEVALUE('Product'[Product]),
    CONCATENATEX
    (
        Channel, 
        "• " & Channel[Channel], 
        UNICHAR(10)&UNICHAR(13) , 
        Channel[Channel]
        )
)

Product Countries = 
IF(
    HASONEVALUE('Product'[Product]),
    CONCATENATEX
    (
        Country, 
        "• " & Country[Country], 
        UNICHAR(10)&UNICHAR(13) , 
        Country[Country]
        )
)
