After you have created a computer profile you can make modifications to it. You can
add or remove packages
add, remove, or edit hardware jobs
edit package parameters and computer properties
When modifying package parameters you can modify parameters for a specific package or for all of the packages in a profile. You can also modify package parameters when you assign the profile to a computer. Settings you make when you assign the package override the parameter settings made when you added the package to the computer profile.
