How to find out if different Nets are connected at a single point

Hello,

In a completed PCB design, is there a way to highlight errors which involve inadvertent connection between two different Nets, either due to tracks and pads cross each other or by incorrect placement of a Net's pad on a copper pour area belonging to a different Net?

I find this very hard to find out in the PCB view or in any of the DRC options ?
If this is presently not available, Can this be added as a feature in the DRC ?

Best Regards,
