[Gmsh] Question about higher order elements

I'm thinking about using Gmsh for a research project which involves 
computing fluid flow fields via a spectral/hp-element method (p>5). I was 
reading through the documentation, and it seems to indicate that higher 
order nodes are assumed to be equispaced. However, if I am not mistaken, 
hp-element codes normally place the high-order nodes at the 
Gauss-Legendre(-Lobatto) points within, for example, a quadrilateral 
"master" element. This is especially nice if your solver uses a nodal basis 
for its shape functions. Is there any way to have Gmsh use a Gauss-Lobatto 
distribution of nodes within a high order element?
