Equipment Lists- Adding a date / time stamp it was created or validated and by who

Looking for options to make internal company requirements a bit easier to manage. At PHI, we require an annual reweigh of all carry on equipment every January. We also require a quarterly validation that the equipment carried on the aircraft matches the equipment list. Adding a name, date, time stamp to each equipment list would be a useful tool for us to manage this. Ideally, this would appear not only on the equipment list itself, but on the front page of aircraft equipment where all equipment lists reside (where you'd select a list to edit, etc).

Presently we have the person just enter name and date on the bottom line of each equipment list, with no weight or arm, just so there's a record.

Not sure how other operators manage this, but I see it useful for all just to have a date last modified and by who.
