One more, please? with the new multiple health bars

Playing with the new multiple health bars in the Conan system, there are four vital stats that need to be tracked. These are Vigor, Wounds, Resolve and Traumas. For my NPC, as I started trying to use the multiple health bars, I chose to only track Vigor and Wounds, and all was good. However, as I was testing setting up a player character with multiple health bars, intent on tracking all four vital stats, I came up against the apparent limit of only three health bars.

Please allow us to have at least one more?
