Found a solution to this:
First, you have to load the redir.lsp found here: C:\Program Files\Autodesk\AutoCAD XXXX\Express.
Then call its function.
Example:Code:(bns_redir path1 path2)
I just searched my ACAD dir for this lisp to find it out.Code:(load "REDIR") (bns_redir "//servername/Projects/" "C:/Users/username/Dropbox/Job Name/")
