Map Source column to output column

[niatos99]

How can i map the source column to the output column?
It is T-sql

For example:

WITH 
	cte_1 AS (

SELECT
LTRIM (RTRIM (MKD.MKD_ABC))	  AS MKD_5
FROM source.ZA01MKD AS MKD

	), 
cte_2 as (
SELECT 
    MKD_5 as MKD_55   
from cte_1)

select
    MKD_55 as Alias_555,
from cte_2

Expected Output:

[MKD_ABC, Alias_555]

Right now i can find the source column via the Traverse_scope, but i cannot map it to the output column.

This can be achieved using column-level lineage. Some examples can be found in the test suite.
