[ccp4bb]: Q: reduce size of Rfree set

Dear all,
I refined a structure against data to 2.3 A, where the Rfree set
included 2600 reflections (5 % of data). I now have data to a much
higher resolution, and putting 5 % of data in the Rfree means 11000
reflections, which is quite a lot. I would like to use a smaller
fraction for the Rfree set (say 1 %). For this, I need only to keep 1
every 5 reflections of the "low resolution" free set.
Any hints on how I can do this ?
