Jiri,
I was sitting here tinkering with the EoL stuff I have, and had an idea. I realized that you are adding additional EoL devices manually to each new NCM release. Why not take a trick from the SAM book, and let us pull device updates like we do for SAM templates? Then we can install only what we need, and your team can keep adding them but it won't require us to upgrade to get the latest info.
Just a thought...
