Importing a DXF shape for use as a Package Keepout

Hi,

I am laying out new circuitry on an existing PCB shape. I have been given DXF files of the board shape and a package keepout area.  I was able to import the board outline, but I am having trouble getting the second shape in as a package keepout.  Is there a way to import a DXF shape and add it as a Package Keepout?  It is an oddball shape that would be a bit of a pain to do manually.

Thanks.
