Data-Only Blueprints/Subclassing Blueprints

Hey, that kinda worked. I can now easily create a blueprint from my existing blueprint. I’m assuming I’m looking at something that’s got a ways to go, but the only variables I can modify in my derived blueprint’s defaults are bools (Missing are the arrays and floats). Will these eventually be supported? Is there an alternative method I should use to access and modify the values? (note: i can access the variables in the node graphs, etc. just not in the Defaults)
