Setting Environment Variables in login items in workgroup manager

Hi all,

I am trying to add a network folder login item that includes the users login name in the smb path. For example

smb://server/share/$username

I am able to get the share to mount but I have not been able specify which folder on the share should mount.

I have tried doing this through apple script as well and id does not appear to be working.

does anyone know if this is possible to do via Workgroup Manager?
