There is how I do that:

Use external binary morphs  = on

Save figure with morph to Library.  NEW.cr2

Open the NEW.pmd that is saved with the CR2 in PMDEdit.  Delete all morphs but the one(s) of interest. (If you generate the morph in a stripped version of the figure, there are no other morphs to delete.)  Save the edited NEW.pmd.  Go over to the INJ & REM option and have the program generate Injection and Remove PZ2 for the morph. ( There are options available - make a master dial in BODY, set initial value to 1.0 so that it comes in ON, assign it to a group  that you give it, give the morph a different name. )
