Drag Drop 3D Actor to ---> UMG/UI?

I need to find a way to take a 3D actor and drag him back into the inventory Widget UI. The inventory system is fully drag and drop integrated already.
I know that actors won’t trigger the Widgets Drag detection… so how would I go around being able to implement this… This is one of my last hurdles to get my game to finally ship… I feel like I have a great understanding of Widgets and the UI after 4 months of working on inventory systems, etc, sort of scared of the answer…really hope I didn’t waste 2 years as this is a crucial part of my game.

Ya really need help on this one, even if its hacky… or a workaround…
