We have a Client who is attempting to use Laserfiche in a manner that is similar to WORM but not completely.

According to this Client, with their old Imaging System, they had worm media. They could delete or change images in the system.  All images were written to the volume, and if something was deleted/changed, the old images stayed on the volume and the replacements were written there as well.  The links from the imaging system database to the old images were lost, but nothing was ever deleted off of the media.  

Client is looking at the possibility of something similarly in Laserfiche.  Users have to be able to delete/change images within the system, but that historical record of images should remain.  Is this possible?
