Attached Link: How can I make probs out of more than one obj file ???

I build this bed in MAX and exported as OBJ. These are two different files because so modelling and UV-Mapping/Texturing was much easier. I imported all in POSER and put things in place. I added color and maps but I'm not able to make "ONE" prob out of it. I only get the file that is selected. I still could make a figure (cr2 file) out of it, using the Hierachy Editor. If I reload the figure I get the objects but all colors and maps are gone.
