Keep power nets separate in a hiearchical design

Hello,

Say that I instantiate the same block four times in a schematic, I’m using the SUBDESING_SUFFIX attribute to keep the same location value in each instance, for example, R1 becomes R1CH1 in channel 1, R1CH2 in channel 2 and so forth. Even though all four blocks are identical I want to use separate voltage nets for each instance. Each block has, let’s say, five schematic pages where one of these pages contains the circuitry for generating the desired voltages. The voltages is supposed to reach the other four pages in the block but not out of the instance.

Here is my dilemma/question. I have used global power ports but now I realize that all power nets are merged together in the netlist since they are global. That was not what I wanted to achieve. How can I solve this dilemma? Should I use off-page connectors instead or can I attach some kind of property to the power ports to keep them in each instance?
