Auto-mapping for identical source and destination nodes

### Which Data Mapper Version are you using ?

v2

### Describe the Bug with repro steps

Use case:

- When the source and destination nodes are identical, users should have an option to auto-map nodes based on name matching
- Users should be able to override or modify specific fields as needed while retaining the auto-mapped structure.
- This feature should be optional to avoid unintended mappings

Expected Behavior:

- A mechanism (e.g., a toggle or button) to enable auto-mapping based on field/node name similarity.
- Auto-map functionality should maintain parent-child relationships where applicable.
- Users should still have the flexibility to modify specific fields manually.
