[phenixbb] Multiple pdb entries in phenix.fmodel

Hi, I just wonder for the huge systems which have been split multiple pdb entries, if I provide all the pdb files in a single script of phenix.refine: phenix.fmodel A.pdb B.pdb C.pdb data.mtz whether everything will go correctly? Or I have to merge them into a single pdb and renumber all atoms sequentially? Thanks!
