JDL - Probably not the answer you want (or that I wanted...) but when I called support about this, they told me the only way to remove old/superseded/un-needed patches was to totally uninstall the update manager and then re-install.
I brought this up to our TAM and he did some research and claimed the same. After I calmed down, I expressed my dismay that there was no way to better manage the available patches and asked this be looked at and submitted as a request for enhanmencement in future versions.
My issue started when we decide to not use VUM for patching the VMs themselves, unfortunately, my system had already downloaded patches for Windows & Linux.
I'm actually in the middle of the re-install now and will post more info after completed.
