Flip vertical levels in .meta

[bluefinweiwei]

Is it possible to reverse the vertical coordinate in meta files?
Just like extracting a slab of a surface-layer field:
[ugrs(:,1)]
standard_name = x_wind_at_surface_adjacent_layer
long_name = zonal wind at lowest model layer
units = m s-1
dimensions = (horizontal_loop_extent)
type = real
kind = kind_phys

Is it possible to do [ugrs(:,::-1)] to directly pass in variables that are flipped in vertical? Thanks!

Not with Prebuild. In Capgen this is currently possible.

Look forward. The users can know ahead that the levels are flipped. Thanks for the quick response.
