Easier way to manage software installation?

Hello,

I am having a really difficult time trying to understand how the software deployment works. I can get software installed and uninstalled, but I can't believe that I have to make or edit a configuration every single time I want to install or uninstall software from a few computers...

I this really the way to do it? Create a configuration for every installation or removal?

I was "hoping" that I could just create a package with install and uninstall parameters, scripts, etc, and that the Desktop Central would then create an install and uninstall configuration for me, to which i can simply assign users or computers on which I want to install the software. Of course, a user or computer cannot be in an install and uninstall configuration, of the same program, at the same time (User cannot be in the Install and Uninstall configuration of PowerIso for example, just one or the other), however, with how it is now, I can add users to an install and uninstall configuration at the same time, making the agent go crazy with installing and uninstalling the software.

So, am I misunderstanding the way to manage the software that I want to install for a user or computer, or is this indeed a "less-than-optimal" implementation at this point?
