Hi, if I understood your question correctly, then one of 13 scenarios described here:
http://phenix-online.org/phenixwebsite_static/mainsite/files/newsletter/CCN_2015_07.pdf#page=12 fits your situation and you should be able to handle it in refinement all right. For more specific advice please feel free to contact me directly (off list) with relevant files. Good luck!
