1) Multiple 3D Harnesses in single Drawing with same connector. 

Creating multiple branch from single harness and any time addition or replacing must be possible

2) Customization in BOM of Flatten Drawings of Harnesses.

I want to add resistance in wire property, which i can use at the time of creating reports, Excel out

3) Length Should be change with drag of  component in 3D environment.

After routing, connector location change is possible or not? If yes then wire route or harness must be dynamically updated
