Hmm - this finally was rather deprecated - there are some less happy consequences to have all reflections in a particular resolution shell excluded. If your NCS means there is pseudo- symmetry in the diffraction and it would be possible to have a cell with higher point symmetry (an example might be be Pmmm or P4mm if a(Pmmm) ~ b(Pmmmm). ) then you could assign freer flags in the higher symmetry group and extend then to the lower...
What is your cell, and do you know the NCS operators?
