Isolate same properties net and Via from plane shape.

Version 2

    Most of the time We would like to isolate same properties net and Via from plane shape. Example: When we route two current sensing nets (Signal and ground) by Kelvin routing, we need to isolate ground net and Via with ground plane by using plane obstruct. It will be good if tool has inbuilt function to isolate same properties net and Via from plane shape.
