Reset D&D slide to not answered correctly OnEnter

Hello,  I am working on a training module that contains a drag and drop slide, where the learner drags an object to another section of the screen, as if they are in a software application with draggable widgets (screenshots used to simulate the application).  There is only one drag source and one target on the slide.  Infinite attempts. Not reported to a Quiz.  I used a blank slide and added the D&D interactivity. Using 2019 Release 11.5.1.499 on Windows 10

The initial setup works perfectly, BUT...once the correct D&D is completed (on success action automatically goes to the next slide that shows what they would see in the application on a successful D&D), the learner can never go back and do it again as the D&D has already happened and the source is gone.  This section of the module is a part of a "practice" section, after being shown what to do.  We allow them to go back and practice as many time as they want, but the D&D, once correct, cannot be done again. We have advanced and/or shared actions onenter of the practice slides to reset everything so they can practice over and over again, but I cannot find a way to do this with the D&D interactivity.  Is this possible (resetting the D&D slide to NOT having been aready answered correctly so that the action can be done again)?  No submit, undo or reset buttons used. Would love a D&D answered correctly variable to assign back to zero!

Any help/ideas are greatly appreciated.

Gracias!
