Is There a Requirement Tree in Unreal Engine?

I've never had a whole, I've had a lot of crashes from that replace or rename and all that. And it's much faster for me to use that most of the time than to get my hands all the way deep inside of C++. But I would love to honestly have a chance to dive more into that. Most of my projects are pretty much just fun projects for me. So I haven't had an incentive.
