Parabolic superelevation in Geopak or Roadway Designer

I'm trying to see if we can make Geopak create a parabolic superelevation.  We are doing a project that is utilizing TxDOT roadway criteria and TxDOT requires a parabolic superlevation transition.  Here is a link to the exhibit that shows what I'm talking about:  http://onlinemanuals.txdot.gov/txdotmanuals/rdw/2-1.pdf.  If Geopak will do it, then I'll just create an input file from that and load into Roadway Designer.  I tried to see about creating an *.sup file based on TxDOT criteria for Roadway Designer but not sure I understand the components of that input file.  Plus, not sure it will apply a parabloc transition.
