YOu only seem to have one SPP loaded so this is the only baseline. You can use this baseline in SIM to assign this to servers or if you still use VCA to select this as the only baseline. You can upload any SPP you need or enable the autodownload. I always place my SPP's in separate directories in the Repository directory so i can keep them apart.
This way i can delete folders as soon as i don't need older SPP's.
