Rats Display

I am routing out to an FPGA from a connector and I have flexibility to perform pin-swapping based on the layout when I get close to the FPGA.   As a result, I have many uncompleted clines that need to be connected to the FPGA.  It would be very helpful to have the Rats nest lines displayed from the end of the clines even if the manhattan distance of that point is further away from the FPGA pin than the connector pin.  The rats lines continue to snap back to the origin of the net at the connector pin.  Is there a way to change the display of the rats to achieve this?  Thanks in advance for the help.  (OrCAD PCB Editor v 16.3)

     Hopefully the attached photos will explain it is possible

    Hello - I don't see the "Drawing Options" Menu in my Editor.  I am using OrCAD PCB Editor 16.3

    Probably the best thing right now is to crawl through each menu item and get to know each sub-menu below.

    These kinds of settings are all found *somewhere* in the Setup menu or its sub-menus.  In this case it can be found under Setup->Design Parameters and then under the display tab.  

    Cadence changes menu names like the wind changes direction...not sure where they get that internal direction from -- it's frustrating.  My menu was from an earlier edition.

    "Why they don't allow double attachments..."

    Because it's a hopelessly lame forum? Only one of many shocking limitations...
