Remember that you can always do some simple (but powerfull) operations
within SFTOOLS (*). So using something like

  read refmac.mtz
  CALC col resol = 0.5 stol /
  select col FP = absent
  absent col FWT  if col resol < 3.0
  absent col PHWT if col resol < 3.0
  delete col resol
  select all
  write refmac_new.mtz
  
might/should do the trick: setting all filled-in FWT/PHWT values to a
MNF (missing-number-flag) for reflections with resolution higher than
3A. So you should only have filled-in 2mFo-DFc valeus for the low-res
data (3A and lower).

But check those commands above (typed from memory)

Cheers

Clemens

(*) there is very little one can't do with SFTOOLS
