Dynamic Pivot SQL in the Common Table Expression (CTE) - sql-server

Question

I am trying to Pivot a result of a CTE. Due to the privacy laws i cannot put my query and resultset here but the example looks like the below:
WITH CTE1
AS ( select ....)
,CTE2
AS (Select...)
,CTE3
as (Select...)
Below is the result of my CTE2:
and i want the result as
The main issue i am having here is to pivot the resultset with multiple and dynamic Pivot columns between CTE2 and CTE3 as i need to use the Pivot data in CTE3. Is there any solution without changing the CTE's to TempTable? Any help will be appreciated.

I think it's going to be something like this.
Dynamic Pivot:
DECLARE #query VARCHAR(4000)
DECLARE #years VARCHAR(2000)
SELECT #years = STUFF(( SELECT DISTINCT'],[' + [factor_label]
FROM [TEMP_lacp_factors]
ORDER BY '],[' + [factor_label]
FOR XML PATH('')
), 1, 2, '') + ']'
SET #query =
'SELECT * FROM
(
SELECT [date_],[issue_id],[cusip],[Factor_value],[factor_label]
FROM [TEMP_lacp_factors]
)t
PIVOT (MAX([factor_value]) FOR [factor_label]
IN ('+#years+')) AS pvt'
EXECUTE (#query)
Dynamic Pivot and Select Into:
-- Drop the table; you create it dynamically
Drop Table tempTable
--Start creating all objects for Dyanmic Pivot
DECLARE #query VARCHAR(4000)
DECLARE #years VARCHAR(2000)
SELECT #years = STUFF(( SELECT DISTINCT'],[' + [factor_label]
FROM [TEMP_lacp_factors]
ORDER BY '],[' + [factor_label]
FOR XML PATH('')
), 1, 2, '') + ']'
SET #query =
-- Objects that are created above, are put into the table you are about to create below
'SELECT * INTO tempTable FROM (SELECT * FROM
(
SELECT [date_],[issue_id],[cusip],[Factor_value],[factor_label]
FROM [TEMP_lacp_factors]
)t
PIVOT (MAX([factor_value]) FOR [factor_label]
IN ('+#years+')) AS pvt) X'
EXECUTE (#query)
-- Select everything from the dynamically created table ('tempTable') to see results
Select * from tempTable
I'm not 100% sure what you are doing, so it's just a best guess.
