I did this in my Tahoe just for that reason.
Basically you have a relay powering the low beams. Pin 85 to ground and 86 to low beam 12v. What you would do is cut the 85 ground wire in half and connect on side to the 30 on the second relay and the other to 87. ground pin 85 and connect 86 to parking lights positive. What this does is cutoff ground from the first relay preventing it from opening when 'flash to pass' during the day. When parking lights are on, ground is restored allowing the relay to open for low beams.
