Captivate Drag and Drop reset wrong answers only

Hi I was wondering if someone could help with this simple problem I've been having an issue with creating a drag-and-drop in Captivate 9. It is a simple missing word drag and drop where the user drags words into a sentence. The problem I'm having is when the user presses the Submit button I want all the correct answers to stay on their correct drop targets and all the wrong answers to bounce back to their starting position. This was easy to do using Infosemantics drag and drop widget but their widget is not HTML5 compatible so I need to find another solution. This should be simple to achieve but I can't see how! At the moment if you don't get everything correct all drag objects bounce back to their original starting position. Any thoughts on how to achieve this?
