Appending a volume image to a wim file and setting the its flags

Hi

I am using Windows 8.1 Update and Windows ADK.

If I use the command

Dism /Commit-Image /MountDir:"<Mount_Directory_Path>" /Append /CheckIntegrity

to add a volume image modified, how should I do to set the name and description of the new image without using the ImageX command?

Thanks

Bye
