17.4 - Start differential pair with non-zero skew?

Question

PCB Editor 17.4 
 I have a weird edge case where we're using a "hybrid" connector to bring Ethernet onto a PCB. The manufacturer calls it a hybrid connector because one row of pins is SMD, while the other row are through-hole. Per their application note, differential pairs get split across a through-hole pin and an SMD pin, which introduces a fixed amount of skew of 26ps into the pair due to the extra length of the through-hole pin geometry. 
 However, differential pair constraints - as far as I know - assume that there's zero skew in the signal when launching from pads into a pair. Is there a way to tell the constraint manager that the pair starts out with a certain amount of skew - e.g., that this net is 26ps slower than this second net? This would create a DRC telling me to add that 26ps of delay back into the second net, bringing the pair back into spec. 
 Thanks!

You could try using the Pin Delay option. Take a look at the Diff Pair worksheet (or Prop Delay ones) and add a value for the pinpair in question. That will allow you to enter the required values and then phase (static and dynamic) or delay will use that value.
