feature request: Berry curvature of the Nth band at the Fermi level

[Dongsheng-Wen]

Dear Dr. Wu,

I'm using wanniertools for my Berry curvature calculations for a k-plane slice. I checked the output Berrycurvature.dat file, it has 18 columns of data.
The first six columns are coordinates.
Columns 7-9 are labelled as 'Sum over 1-NumOccupied bands'
Columns 10-12 are 'values at NumOccupied'th band'
Columns 13-15 are 'Sum below Fermi level'
Columns 16-18 are 'values at Fermi level'

These results are very useful. I'm interested in the ones at the Fermi level, I realized that 'values at Fermi level' are actually for all the bands (is this correct?). If I want to get the values at the Fermi level for only one band (Numoccupied one), is there a way to do it?

Regards,
Dongsheng
