Assignment of cdc net labels in Chipscope

I have a system where a Virtex 6 and a Spartan 6 are daisy chained using a single JTAG connection for the programming pod.  When using Chipscope the first FPGA can be configured with the net labels that were setup in the cdc file but when I use Chipscope on the the second FPGA, all I get are Dataport and Triggerport names (not the net labels that were assigned in the setup of the cdc file for the second FPGA).  If I manually translate the Dataport and Triggerport signals, it does seem to trigger and display the proper waveforms.  Just terribly inconvenient to have to create a manual list of signal names.  

 

Just to reiterate, it only happens to the second FPGA of a daisy chain.

Just noticed that while the actual timing diagram is not displayed the Net Names are assigned to the first FPGA in the chain.

 

Still not very useful.

 

By the lack of response I guess nobody daisy chains FPGA's and uses Chipscope.
