Query History of specific columns from a system-versioned table

I have a SQL Server system-versioned table with ~20 columns, all of which hold changing values over time. I am trying to get the changed values for only a subset of the columns along with their respective validity columns.

Some example data:

And the desired output:

Basically, I want to get the validity periods for column Name and Company while ignoring the changes in Location but using the Sysstartime/sysendtime values created when changing location.

It is possible that I will need additional columns ignoring changes to undesired columns.

What query would give me the desired result?

Use Self-join in first CTE to identify changes in Name. In second CTE groups consecutive records. and finally consolidates them, calculating the earliest start and latest end times for each continuous employment period per company:

WITH Previous AS (
    SELECT 
        curr.Name,
        curr.Company,
        curr.SysStartTime,
        curr.SysEndTime,
        prev.Company AS PrevCompany
    FROM EmployeeHistory curr
    LEFT JOIN EmployeeHistory prev
        ON curr.Name = prev.Name 
        AND curr.SysStartTime = prev.SysEndTime
)
, Grouped AS (
    SELECT *,
        SUM(CASE WHEN Company <> PrevCompany OR PrevCompany IS NULL THEN 1 ELSE 0 END)
        OVER (PARTITION BY Name ORDER BY SysStartTime ROWS UNBOUNDED PRECEDING) AS GroupID
    FROM Previous
)
SELECT 
    Name,
    Company,
    MIN(SysStartTime) AS SysStartTime,
    MAX(SysEndTime) AS SysEndTime
FROM Grouped
GROUP BY Name, Company, GroupID
ORDER BY Name, SysStartTime;
