The spawned props approach has the advantage that your CR2s will be smaller, and you'll get more efficient memory use in Poser (hence, more characters possible per scene). For the 3 series figures from DAZ, there's a program called injection pose builder which will take a character and make INJ and REM poses for that character. That's the usual way of distributing characters for V3 and her ilk. For non-injection characters, you can make a MOR file which is basically a pose file with everything except the morph channels stripped out. But if it's for your own use, what you're doing is the best way, if tedious. There may be a script that will help with this. Just shout "ockham!" :) I don't have my collection to hand, and I can't remember what's in there...
