[phenixbb] molecular replacement keeping hetatms?

Can I do molecular replacement with phenix/phaser, keeping all the waters from the first model from the first data set?

From here ( http://www.phaser.cimr.cam.ac.uk/index.php/Molecular_Replacement#WATER), I should change all the HOH labels to something like WWW. Then I guess that I should put HOH labels again in the solution model, for the following refinement in phenix.refine.

Is that it?... Any suggestions? thanks again!
