I have a single one-line command I want to deploy to the self service portal, so that if users run into a certain problem, they go to the SSP and click Install and it fixes the problem.  Its not an executable or deployment package or anything, just a single command-prompt command that needs to be on-demand.  How do I do this?

I know the command works fine because if I test it in Command Prompt it goes without a hitch.  I tried deploying as a 'package' that amounts to "CMD.exe "thing.bat"" but not only does it not work when run that way, it puts the Self Service Portal into an infinite 'installing' loop that requires me to kill the SSP process via taskmanager.

So, I know I can deploy the command with as a targeted Configuration, but I specifically want it as on-command in the SSP, so how do I do that?
