Hi Tom,
Here is a way you can copy an existing component monitor to another template/
1) Go to your SAM Settings page and click "Manage Component Monitors within Templates".
2) Group by Template and select your original template with the component monitor you want to copy. Check the box next to the PowerShell monitor and click the Copy to button - "Copy to Application Monitor Template". (Not sure why the image below is distorted, it's clear if you click on it)
3) Select the template(s) you want to copy the component monitor to and click Submit.
Hope this helps.
Steve
