Drag and drop
The model browser supports drag-and-drop operations for bodies/sub-models/models. Drag and drop can be done within or across the model.
Users can also select bodies in the GUI and drop them to the required model in the browser using Shift + Drag.
When we drag and drop across the model, if there exists a body with the same name, it will show an option to replace or transfer. Based on user preference, it will do the operation.

When we drag and drop models, the model grouping gets maintained as a sub-model in the destination model.
