Here's an example using Transposer. I find that putting dummy props in the Poser scene allows me to position the poser figures better. The other key annoying issue I have with Transposer is having to reset all of the materials each time I import the scene. It should be possible to resave the scene and then have it refreshed in Carrara but I've not been using that.
