Deploying DCOM settings with script or GPO.

I have a domain where workstations require DCOMCNFG to make DCOM settings for SIEM monitoring and for a production app's.
It's not too tough to make the settings manually but it's still time-consuming and tedious.
Having a GPO or script to set them would likely be very useful.
IF there were a script, I'd still prefer to deploy via GPO because of Windows updates making changes otherwise.


To be specific, using DCOMCNFG, we need to open My Computer properties and
1) set DOM Security / Access Permissions /Edit Limits by adding adding missing Permissions for Group or User Names and adding names and permissions if missing and
2) to do the same for DOM Security / Launch and Activation Permissions /Edit Limits
And going down the tree hierarchy to Console Root \ Computers \ My Computer \ DCOM Config \ Windows Management and Instrumentation \ Properties \ Security \ Launch and Activation Permissions: adding missing Permissions for Group or User Names and adding names and permissions if missing.

In my research toward doing this, I've not found anything that's very satisfying.  
I'm happy to read and to develop but a better starting point would sure help!
Any suggestions would be appreciated.
