Do you mean list all non-connected net wires and automatically jumping to it?
DRC Checker will report all hangling/dangling nets and list the hyperlinks in the outout window(Tools-> Verify Connectivity-DRC-108).
Sorry to be unclear. I am asking about graphically showing one net "jumping" another when they are not connected. usually with a small half circle.

No, the only indication that nets are not connected is the absence of a solder dot. It doesn't support the style you refer to.
