What JAFO suggesteed is probably the simplest way. Make sure all the morphs you want to include in the set are expressed at a value of 1.0, or whatever relative values look correct to give the final effect you are after. Make sure that any morphs you don't want included in the set are set to zero.  From the Figure menu, select 'Create Full Body Morph', name it something descriptive (eg "Explode"). Your new FBM dial will be placed in the BODY actor. Set all the individual morphs back to zero. You should be able to use 'Restore > Figure' (Ctrl+Shift+F) to do  that, unless the figure has been memorized in a none zero starte.

An alternative to creating an FBM in Poser, is to write the ERC for the FBM directly into the cr2.  See the post "How to write ERC code?" on this page.
