Drop States When Drop Target Is "None" Not Working?

Old thread but relevant to my current project. 

Two things with this limited functionality. Drag and Drop will not easily allow you to show all draggable items at the same time AND tally correct/incorrect based on sequence. Ex. - I'm working on a medical donning and doffing PPE. There is a specific order the user has to follow. Additionally, they will have an entire bin of equipment - so only giving one piece of equipment at a time is impractical. I have a trigger monster to accomplish this but it's so tedious. Why can't you just drag and drop in sequence (specific order) AND have all draggables displayed and interactive at the same time? 

The other thing - Drop Incorrect State is tallying if I drop the item in blank space - counts against the user. It should only do this when I drop on the incorrect target. Now I can create triggers to deal with this, but then it hurts the ability snap item back to original location. So then I have to make motion paths....

Finally - if you drop an object on the incorrect target, the state changes to drop incorrect, and the item doesn't snap back - making it impossible to try again if you are giving the learner three attempts. 

Like I said, I have a work around - but the triggers are outrageous.
