graphviz: left/right align nodes instead of centering?

Is there any way to get graphviz to left-align or right-align nodes in the same rank, instead of centering?

   digraph h {
     rankdir=LR;

     node [shape=record,height=.08,fontsize=11];

     elk[label="elk|I am an American Elk"];

     buffalo[label="buffalo|Just a buffalo|everywhere I go|people know the part I'm playing"];

     cow[label="cow|moo"];

     moose[label="Bullwinkle J. Moose|Hey Rocky, watch me pull a rabbit out of my hat!"];

     zoo [label="zoo|<p0>|<p1>|<p2>|<p3>"];

     zoo:p0 -> elk;
     zoo:p1 -> cow;
     zoo:p2 -> moose;
     zoo:p3 -> buffalo;
   }
