you can do it in phenix.refine. If you assign one molecule an altLoc A
and the other one altLoc B, and have them under the same residue name
and chain id, their occupancies will be refined and the sum of them will
be constrained to exactly 1. This is explained in phenix.refine manual:
If you still having trouble with this, then you can just send me your
PDB file or its fraction containing the ligands in question, and I will
help you from there.
