CCG Toolkit - changing some values

I’m currently trying to make something with CCG Toolkit, but I’m having a hard time with it, since I’m new to making games and using game engines. I want to change some values like max health and max mana. Is there an easy way to do that with this toolkit? It would be nice if I don’t have to change values in the whole hierarchy or make graphs from scratch if I want to make changes to some of the gameplay mechanics. Also, can anyone recommend a way to learn this specific toolkit? I have some programming experience, but it’s still hard for me to translate lines of code in my head to the visual style of a BP.
