Creating existing UMG components in blueprint

I need to populate a horizontal box with items with spaces between them. In loop I create instances of my widget and add them to the horizontal box. I’m trying to add Spacer component in-between but I can’t find a way to create the widget itself:

It seems like I need to create a separate blueprint with this spacer but it seems to be quite a tedious way, needed for every new list. Is there a better way?
