Quote - Guys:

Acadia asked "Is there a way to delete or 'un-inject" the ones that are sitting at zero?  "

I know she didn't say "automatically" but clearly that's what any person would be thinking about who is not an automaton with infinite free time and nothing to do.

She didn't ask "Is there a way to accomplish this task through the excruciating process of looking at each of my morph dials, finding the corresponding REM icon, and clicking on it. I have injected all 212 head morphs, adjusted the 13 I like, now how would I go about manually removing the other 199 morphs one by one."

I'm not aware of any other way to do it either.  Once they are injected they stay injected
until they are removed.  And you either take them out one at a time or you take them
all out at once.  The only other solutions are like what you said, spawn a morph target,
and then remove them all at once, or write down the settings of interest and remove
all of them and then just inject back in the ones you have written down.
Or just live with a bunch of unused dials and a big CR2  or PZ3 file.
But it doesn't really take that long to remove them one by one either.
