How can I do multiple segmentations of the same bodypart without automatically transferring the setup from one to the other?

Dear 3DSlicer-Community,
I am facing a Problem right now and could not find a solution for that here yet.
I want to create different Segmentations of the same part (here a vertebra) but one, showing the whole vertebra, the other only the cancellous bone and onther one only the cortical shell. Whenever I change for example the Threshold in one of the segmentation it is changed also in the other ones. How can I do the segmentation independantely from the setup of the other?
Thanks a lot in advance!
Best wishes
