Randomly Setting Cost Values of Nav Area

Is there a way to randomly appoint values to the cost values of custom nav areas using blueprints? I would like to randomly generate values to input into the cost values so each AI would have a different path it would take to reach a destination. I’ve seen this post (
https://answers.unrealengine.com/questions/91843/how-to-change-navigation-cost-in-realtime.html) where Rama suggested to do it using C++ but other than this, is there no other way? Does Rama’s Victory Plugin include anything that could aid in this? Thanks for any help in advance :slight_smile:
