Need CMDLet for downloading software update
This functionality already exists via the Save-CMSoftwareUpdate

Save-CMSoftwareUpdate should accomplish this. If we are misunderstanding the scenario or this cmdlet isn't doing what you expect please let us know.
This cmdlet already exist, Save-CMSoftwareUpdate. If you do not have this cmdlet be sure to download the latest ConfigMgr cmdlet Library tool, to update your cmdlets.
