LTspice plotting phase between signals

I am designing a phase shift circuit and it would be ideal if the phase between two signals could be plotted. At the moment I use the amplitude difference between the two and this works to an extent, but the result isn't particularly meaningful to me. (It's just an amplitude figure.) So, is there a function or way to plot the phase between two (identical frequency) signals?

Switch to AC analysis and it will automatically plot phase (dotted line) along with the amplitude.
Sure it shows phase, but the question was a phase difference. How do I plot that in AC analysis please? I tried plotting V(n001)-V(n002) but that is substracting amplitudes and kind of averaging the phase. It doesn't plot the phase difference. I also tried plotting ph(V(n001))-ph(V(n002)) but that also wasn't giving me phase difference :(
