Just for those curious as "how to"

 

I think I've kinda got a solution worked out; bit it seems kinda messy...Let me know what you think....

What I did was go to the group tool and select the hood part then did an invert and create prop.

This created the figure without the hood but there were a few fiddly left behind polys from the hood so I continued to repeat the process, select hood parts, invert, create prop, etc until I got a clean break off.

Next I added my new unit as a prop, I loaded up the original figure and set the main body parts visibility to false and positioned the original figure so the doors and other parts matched up with my new "hoodless" prop. Then I set the relevant parent items with Change Parent and Set Figure parent so the "hoodless" prop wouldn't slide around when moving the whole figure.

Next added this to my library as a full figure in Character Library et viola !

I now have a nice kitchen unit sans extractor hood. Was a bit of a chore to do but finally got there in the end !
