Can i use CreateDefaultSubObject in blueprint?

In c++ class, we can use CreateDefaultSubObject to create a component variable. But when i use blueprint, i want to use this same operation, but i can’t find the corresponding function in blueprint like CreateDefaultSubObject. May i only use the AddComponent to create a component variable?
I will be so appreciate if anyone can help, thanks!

Thank you very much !

Can you change this to an answer so the question can be resolved?

You are right, in Blueprint Editor you dont need to call some function - just use AddComponent and configure names and hierarchy with mouse and keyboard. And nothing more.
