Capture Hierarchy- using global power pins for signal nets?

Question

We have a RF design that we decided to use a hierarchical schematic. This is primarily to make it easier to follow (30+ pages). The designer added all ports for the RF paths, but we just realized that we are missing ports for all digital logic. I can add the ports, but it will make a mess of our pretty block diagram. I was considering replacing the off-page symbols with global power symbols. Can someone give me a reason not to do this? 
 
 Thanks

If you place ground symbols instead of ports in a hierarchical block, the hierarchical pins will not get generated. This is because hierarchical pins are used to connect the ports of a hierarchical block to the ports of its parent block, and if there are no ports to connect, there will be no hierarchical pins. Hierarchical ports and hierarchical pins are used to connect the different levels of a hierarchical block to each other.
