Is there any way using the <REQUIRES></REQUIRES> and <EXCLUDES></EXCLUDES> to check to see if a Power is Constant or Persistent? It works great if a power as been assigned the Advantages of Constant and Persistent. I'm looking for a way to check to see if the power is already Constant or Persistent inherently.
For example, if I create a new MODIFIER and include <REQUIRES>CONSTANT</REQUIRES>, it will be available for a power like Blast that has been given the Advantage of Constant. However, it is not available for a power like Invisibility even though it is inherently Constant and the Constant Advantage does not need to be added. I'd like for the new MODIFIER to appear for Invisibility, too.
