PIVOT UNPIVOT HIERARCHY repetition of levels issue

I happened to solve one business case in my work.
here is my source table

Source
Name	Parent_key	Child_key	Level
CEO	1	1	0
Director Finance	1	2	1
Director Marketting	1	3	1
Project Manager	2	21	3
Project Manager	3	31	3
Team Lead	21	211	4
Team Lead	21	212	4
Team Lead	21	213	4
Victim (me)	213	2131	5

I'd like to TSQL Query in order to get output as follows.

Expected Output
Name	Level0	Level1	Level2	Level3	Level4	Level5
CEO	1	1	1	1	1	1
Director Finance	1	2	2	2	2	2
Director Marketting	1	3	3	3	3	3
Project Manager	1	2	21	21	21	21
Project Manager	1	3	31	31	31	31
Team Lead	1	2	21	211	211	211
Team Lead	1	2	21	212	212	212
Team Lead	1	2	21	213	213	213
Victim (me)	1	2	21	213	2131	2131

I got the output at different levels by using a CTE & Pivot, 

Name	Level0	Level1	Level2	Level3	Level4	Level5
CEO	1
Director Finance		2
Director Marketting		3
Project Manager			21
Project Manager			31
Team Lead				211
Team Lead				212
Team Lead				213
Victim (me)					2131

but I struggled a lot to repeat parent levels values to the top most parent. also duplicate the bottom most child to the rest of all levels.

hence ended up writing the output in a temporary table and keep updating it.. (though I hate it, I need to do it.)

if you have any better solution, kindly let me know?
