Workflow Artifacts

Our make files place the binaries as sibling of the workflow directory 
like so:

...\projects
       myproject\
          src\
       output_binaries\
          bin\

In the Administration->Projects->Workflow->Artifacts tab there doesn't 
seem to be a way to recurse back a directory.  So, it starts at 
myproject\ and I can't find a way to get to ..\output_binaries\.  I 
tried changing the Base Directory to ..\output_binaries but that doesn't 
work.  As a stop-gap solution I am running a move command in the 
build/job configuration that moves the output_binaries directory to a 
sub-directory of myproject to look like this:

...\projects
       myproject\
          src\
          output_binaries\
              bin\

By doing that I can get to the directory with the binaries to public the 
artifacts.

Is there a way I can do this without the seemingly haphazard move command?
