Add all fields to Dynamic Groups
Please add all fields that are available via Get-AzureADDevice to the list of what can be used for Dynamic Groups.
I would like to be able to use DeviceTrustType and DirSyncEnabled to define dynamic groups for use with Intune.
For all DeviceTrustType=serverAD (Hybrid joined) add "Always on VPN", etc.
It does sound like there are other "Hidden" attributes also. Hopefully those too can be surfaced via Get-AzureADDevice and also be allowed in dynamic groups.
