Paul Turley discusses work within the community to get Reporting Services cmdlets:
We (along with Aaron Nelson, Data Platform MVP & Chrissy LeMaire, PowerShell MVP) are working with the SQL Server product teams to recommend the first set of CmdLets that we would like to see added to the PowerShell libraries. Please help us by posting comments with your suggestions. What are the most important SSRS-related tasks that you would like to automate using PS? Give us your top five or so.
I’m glad to see Reporting Services get some Powershell love.
