Hey there, @Anonymous.
Currently, there is no available report which shows your unused items. I have another report you can pull up.
You can pull up the Transaction Valuation report. This report shows the latest transaction that uses the product.
To pull up the account, you can search for it in the Reports Center.
Also, you can save the report by clicking on Memorize on the top part of the report.
Please leave a comment below if you have any other questions.
