Adding Multiple Child UUserWidgets to the screen efficiently. C++

Hi,

Suppose you have a HUD. Also Suppose Child_1_Widget, … ,Child_n_Widget are all extending UUserWidget.
I want to display all the children at some point in time to the HUD.

My current method:

Inside HUD header I would place:

	UPROPERTY(EditDefaultsOnly, Category = "ChildWidgets")
		TSubclassOf<UUserWidget> Child_1_Widget;

	UPROPERTY()
		class UChild_1_Widget* Child_1;
.
.
.
	UPROPERTY(EditDefaultsOnly, Category = "ChildWidgets")
		TSubclassOf<UUserWidget> Child_n_WidgetClass;

	UPROPERTY()
		class UChild_n_Widget* Child_n;

Inside the HUD source file i would first include the files

  #include "Child_1_Widget.h"
  ...
  #include "Child_n_Widget.h"

Furtherdown I would make the following function for each Child_i_Widget:

  void AProjectHUD::Show_Child_1_Widget()
    {
    	if (Child_1_WidgetClass)
    	{
    		if (!Child_1)
    			Child_1= CreateWidget<UChild_1_Widget>(GetWorld(), Child_1_WidgetClass);
    
    		if (Child_1) {
    
    			if (!Child_1->IsInViewport())
    				Child_1->AddToViewport();
    		}
    	}

Afterwards I would extend AHud via blueprints and set all Child_i_WidgetClass’s.

Even tough this method works, I find it quickly becomes unreadable when I add functionality to the Child_I_Widget’s.

My Question is thus: Is there a better way of doing this.

My Idea: Can I Upcast Child_i_Widget to UUserWidget and then call CreateWidget and AddToViewPort. So I have to have 1 function and zero Child_i_Widget headerfiles?
