Merge and Optimize SCM/SCT Base Lines

If you look at the Base lines provided with SCM and SCT there seems to be a lot of duplication. For example there is a baseline for  Windows Server 2008,  Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2 and Window Server 2016.  I am sure that there are duplicated settings in these 5 baselines.

So I am looking for a way to extract the following base lines from them 

1. Windows Server - A base line of the common settings across all 5 base lines.
2. Windows Server 2008 - A base line of the common settings across the 2008 base lines and not in Windows Server 
3. Windows Server 2012 - A base line of the common settings across 2012 base lines and not in Windows Server
4. Windows Server 2016 - A base line of the common settings across 2016 base lines and not in Windows Server
5. Then one per version for the settings that are unique to the version, in other words
   1. Windows Server 2008
   2. Windows Server 2008 R2
   3. Windows Server 2012
   4. Windows Server 2012 R2
   5. Window Server 2016

I would like to do this automatically and not by manually comparing each setting.

TIA
