We often get the request for duplicating and moving multiple segmentations from one image to another.
Use cases could be something like

• segmenting on T1 and having the same masks on T2
• segmenting on CT and having an initial guess for all masks on MR
• segmenting on MR at t=0 and having an initial guess for all masks on MR at t=1

Possible ways to do this could be:

• loading the segmentation node twice and moving it in the data manager (enabling the data manager preference Allow changing of parent node)
• using the image cropper

I would like to collect possible alternatives and pittfalls / drawbacks, especially when it comes to different geometries, whole body segmentation, a large amount of single segmentation nodes etc.
