Client Reports - Forever Boxes

In the back office when digitization is completed and notifies how much space is needed that information goes away in 60 days when the links expire to download.  I would like to have the amount of storage needed to stay somewhere in the associated to that FDC number so later if they are looking at storage would know how much space needed if they had not added before the 60 days.

Example- This order requires 3.4 GB of additional storage needed. would be nice if this could be include in a box separate and reportable.
