You got me interested so I gave it a try. Had a bit of problem with destroying the item once I clicked Yes but (somehow) I managed to overcome this issue. I’m just clearing the blueprint graphs now.
I will post images shortly.
I’m learning blueprints too, so I won’t say this is the best/right way of doing it. Please do correct me if you think I’m doing something wrong! 
You don’t want to create new widget every time you do this so instead just hide it after use and bring it up again when you need it.
Short video below, so you can see how it works for me. Is this what you wanted?
