stft with smaller fwin?

Hi all,

I use stft to make a FFT of my data. 
As long as fwin>=inputwin/2, everything is fine.
But for larger inputwin, when using small fwin (because I need only a coarse 
frequency resolution), the inputwin is adapted automatically to match fwin.

What would be the approach to achieve a coarser frequency resolution?
Calculating the mean over frequency ranges after calling stft seems a bit like 
an overkill?
