Exclude pins of differential pairs?

Hi,

I'm using Allegro 16.3 with the -L performance option.

I have a CAN daisy-chained diff pair that has a header connector and optional termination components connected to the diff pair traces.

These are throwing off the length-match drc.

Is there any way to exclude the trace stubs or pins that are connected to the diff pair in the constraints?

Thanks,

Dan
