Sam, If you are using Cadence Allegro then you can apply the NO_SHAPE_CONNECT property to the pin. This will prevent the pin from connecting to shapes (positive or negative). This will also allow you to add a trace on any other layer to make this connection. If you place the trace on an external layer then you will be able to cut it later.

I need connection to bottom layer only, we would like the ability to cut these traces later after testing. Can I apply a property to pins to do this?
