Blueprint Property Array to Select a Child Component

I have a laser pointer written in C++. I would like to add a property to select a child component to represent the laser mesh and the pointer mesh. How do I make a property that will list the child components and allow one to be selected?

When I do it this way, I do get a list of static mesh components but not the children of this laser pointer component.
