Drag and Drop with Multi Drops in one Object

Hi Everyone,

Hoping someone here can help me out. I'm creating a freeform drag and drop quiz to test some food service training.  The learner has to recreate a food item by placing them in the correct order.  I'm getting stuck with two things:

1:  There are two items that could alternately be added (sour cream on the right, guacamole on the left OR sour cream on the left, guacamole on the right), both would be correct.

2: I had added some elements for misdirection and a "trash can" to discard these items, but it will only allow one item to be placed into the trash can, if I have multiple trash cans I run into problem #1.

Any help would be greatly appreciated!

Thank you!!
