Powershell cmdlet to download all software updates in a Software Update Group
There are Powershell cmdlets to create software update groups and to add software updates to a specific software update group but no cmdlet to download all the updates in a software group - this has to be done manually

We have Save-CMSoftwareUpdate which should provide the desired functionality. If this doesn't meet your criteria or if you're experiencing any problems with this cmdlet, please file a feedback on Connect so we can investigate.
