DS 7.1 Deploy Task - Individual Partition

I notice http://www.symantec.com/docs/HOWTO74592 states that its not possible to deploy individual partitions with the Deploy Image task in DS 7.1.  Is this still the case in the latest version of DS (7.1 SP2 MP1 v4) ?

If so does anyone have a work-around?  I'm deploying Windows 7 and want to preserve an existing D: drive.  When I un-tick the second paritition in my image (under Advanced in the Deploy Image task) and try to save I am prompted to "Provide valid destination partition for single partition deployment."  I can't see any option to do this.
