[How streamlined can I make client installations?]

Right now I do a full scan, find the computer, right click push installation, select credentials, select package, and then next. Then I go to log to see if it worked. Is there a way I can do this in a simpler way like with a command line? (install-default-package comp1, comp2)

[Is there any way to interface RA with powershell and install AV on clients that way?]

For instance making a cmd-let like 'Install-ESETclient comp1'

 

and then it just takes the default installation and attempts an installation?
