I have been tasked with developing a way to "Obsolete" or "Do Not Use" files within a project. We do not want to get rid of them but isolate them so that we have our design trail. We have multiple times when a model revised to the point where it becomes a completely new design. (new model number, etc.) Can EPDM be set (in the workflows) to "lock out" these old designs? Any ideas on how you've all handled this?
