Check numbers on deposits

It would be helpful if a mobile deposit showed the check number that we are depositing somewhere within the number sequencing or on the image. We deposit 2k frequently and seeing the check number with the deposited amount would be beneficial to the customer. Just like in the old days, we could see what checks we deposit with each batch.
