Group Delay of differential responses?

I have a 3-port s-parameter file that I am importing into Eagleware.  I can plot the differential gain (for example) by typing

=db20((.rect[s31]-.rect[s32])/2)

as a measurement.  I would like to plot the group delay of this trace, but I don't know how to do this.  =GD((.rect[s31]-.rect[s32])/2)  does not work.  Is this possible?  Thanks!
