The idea is to have a check box by every item that you wish to turn in & then a 'Submit/Exchange Selected' option at the bottom. This would save time by allowing you to mass turn in items as opposed to the current system of individually turning Items in 1 by 1.
Example:
[X] Item
[X] Item
[X] Item
I have created a mock concept of what this could look like. It's done in paint so lol please excuse it being terrible!

'Toggle' would allow you to set an item to 'Ø' which would prevent it from being selected in a 'Select All'.
