[v8i c#] Reload attachments, instead of reattaching them.

Does anyone know if there is a way to reload attachments (references) instead of re-attaching them. We are running into (Level table?) override issues since Caching the files and then reattaching them via c# addin. We presume that a reload, just like when initiating it from the reference Dialog as a user, will Keep the overrides as they are. Right now they re getting chaotic or just Show up correctly when loading the file a second time (and the file is still available in the Cache).

Sorry I can't give code Details. I'm no developer, just trying to help my colleagues from a user/Administrator Point of view...
