allegro constraint manager

Hi,

I am new to Allegro 15.5.1. Can someone tell me how I can set the constraint manager for differential pair rules by the layer?

What I have basically is a design with 4 inner routing layers that I want to set differential pair rules to. The other two layers have different trace widths and spacing according to the stack up.

I have never used the constraint manager and don't know how to handle this. The online help on the constraint manager does bot have straight step by step process.

Thanks in advance!
