We don’t cover all of them unless it is a Security Bulletin. Or it was something requested and product managment likes to tally what is requested and this is the best way to let them know if you want something, a RFE. You can always make custom content that deploys a Security Advisory. We just don’t do the testing and you would have to do the testing yourself if it is custom content.
So the answer is the same I am afraid. We don’t do all.
So the option is if it isn’t there you can do custom content. And RFE… And product managment evaluates what is currently being published and what resources are available and allocates resources to build content that managment feels is the best use of time and resources based on demand.
