Conformal LP : Merging CPF files.

Hi 

I am using Conformal LowPower license and using it at RTL level. Here multiple
cpf files corresponding to different blocks getting called in the top level cpf.
Please tell me
    1. How can i know the merging of different power-modes in various cpf files?
    2. Can i generate a consolidated CPF file which contains all the data (i.e. power-intent data specified in all CPF files).
    3. Is there any rule CPF_* which takes about merging of different power-modes?

Regards
