Creating an Output Pin in a custom AnimNode?

Hi,

I have a custom AnimNode that contains an FString I would like to print out. However, I can’t seem to find an easy way to create another output pin outside of the Pose. From looking at other questions, it looks like the only way to create an output pin was to have a reference in a UFUNCTION, but since AnimNode is a USTRUCT, I can’t use UFUNCTIONs. I also can’t find any in-engine examples of what I’m looking for, so no help that way as well. Any sort of point in the right direction would be greatly appreciated.
