Oooops Sorry!!
 
I use Injection Magic for custom morphs so cannot help on this cole, sorry!!  Vincebagna, to create body INJ/REM, yes you tick the box 'selected actors only and then scroll to body and highlight it (blue) same for a head only INJ/REM and for all just leave the INJ & Rem poses ticked and untick the 'selected actors only'

Hope that helps, no way have I mastered this little application yet, I'm still sort of bumbling along myself but I do know how utterly frustrating it can be trying to do something with no visible help :(  
For the last few days I have been trying to figure out Miki2 in it, finally sussed it today..yay!!!
