16MB limit

It appears that if our senders upload documents close to the 16mb limit then the signers sign when the sender goes to download the documents they are receiving an error (attached below) which we know is NOT a network connectivity issue.  Is there anyway on the upload screen to provide he users with the sizes of each document and the total.  We understand we can resize documents with specific software but having to qualify / test for example Adobe Pro would be a huge undertaking. 

So would displaying the size be an enhancement request or an easy configuration change.
