Thank you for reminding me.
There is a way to define residue ranges for mixed refinement. I think I did it 
by Boaz's request.

Keyword should be something like (there are ways of selecting particular atoms 
of residues, but I am not sure I have tested that thoroughly):

brefine mixed anisou residues from <resnumber> <chain> to <resnumber> <chain> 
atoms <list of atoms>


Full description of the keywords for mixed refinement is in this document 
(anisotropic refinement section):
http://www.ysbl.york.ac.uk/refmac/data/refmac_news.html

Thus option should be available from the latest ccp4 (but you need to use 
keyword, there is no buttons for this on the interface yet)
Please let me know if it does not do what it is designed for.

Regards
Garib
