Octave analysis in STANAG unit

[nik2013]

I am working on acoustic application, doing different analysis like PSD and Octave. In my actual application, unit is Pascal (Pa). In attached, simplified application it shows default unit of EU.

By default Octave analysis results are in 'db ref 1uPa' (lets say Normal unit). Please refer attached application and screenshots (FP and BD).

But customer wants results in STANAG units, i.e. 'db ref 1uPa/sqrt(Hz)'. (which is directly available in PSD, but not in Octave analysis).

So my question is,

1) Is it logically possible to have STANAG unit for Octave analysis?

2) If yes, how can it be done?

I hope, I am asking proper questions. Please let me know if any more information is required?
