Building Pyramids on NWT_GRD/NWT_GRC fails

I was trying to generate overviews for NWT_GRD and NWT_GRC format sample datasets small_grc.grc and small.grd and keep getting the following error:

"BuildOverviews() not supported for this dataset."

Is it possible to support pyramid generation on these formats?

Note: It is not possible to generate overviews for some GRD/GRC datasets. For datasets that have bands with different datatypes/bit depth, GDAL will not generate OVRs.

Note: See TracTickets for help on using tickets.
