Allegro 16.6 differential line how to set up XNET through a series of resistors and capacitors in series

HI ALL:

           Several sets of differential pairs connect a resistor and a capacitor in each network. How to set XNET to make these groups of differential pairs equal; after create model in signal-model-assignment, the corresponding XNET cannot be completely generated, some networks will be lost, or still Net form, but some are XNET; how to set up XNET that spans two or more passive devices? How is it different from bridging a single passive device。

     best regard！
