Rotated lat/lon grid

Hi ncl-talk,
Our model (COSMO) has a native grid of rotated lat/lon coordinates with
the north pole shifted to a new location. If I understand the logic
behind native grid drawing in NCL correctly, it is not possible to draw
country outlines etc. for a non-transformed data representation. In
order to do that, NCL would have to know the rotated lat/lon projection,
be set to the same parameters as our model, have the tfDoNDCOverlay set
to True.
Is my understanding of this correct?
Is there any other way to convince NCL to draw country outlines
correctly over a non-transformed (native grid) representation of our
model output?
Are there any plans to implement the rotated lat/lon coordinates in NCL?
Thanks for your help,
