If the Kitchen has props parented to each other, you have a basic hierarchy going on. Select the top parent in the hiearchy window and make a figure. All the children will become body parts of the parent, but can still be worked in the scene like props. Might have to adjust jp settings but that should be simple. Done this way, the entire scene loads as a figure. You can hide body parts not needed - same as on a figure. Also, you can move body parts (props) around in the scene - like say that coffee pot (as example, not familar with your kitchen) from the stove top to the table top - via a pose file. You are pretty advanced, so you can no doubt figure all this out. However, if you need more help making this all one big prop-figure (as I call it), I will be glad to walk you through the process. If I were not already bogged down with too many other projects, I would offer to make the conversion for you - but just do not have the time for that. :O)
