Is there (for P8 / PP2010 users) a way to "upgrade" to the full version e.g. purchase just the standalone version minus the python/plugins that we already have?

WW2 is great, the only downside about it is its blocking the whole Poser application until the conversation is finished. So the standalone would be handy. But I hesitate to purchase the full version just for this since I already have the functionality.
