Automatically route the net for all devices which is selected in Layout.

 Hi all,

          I am working on Layout XL. When I select the a net on layout then it will automatically route. For example in layoutXL 3 devices has "net1" connection. If I select "net1" then "net1" routing will be automatically done for those 3 devices.  Is there any command for this directly or need to write code for this. Please suggest me on this.

Thank you,
