Overwrite a display in different folder

In PI Vision - if I use the 'Save As' function to save a display from Folder A to Folder B and that display name already exists in the destination folder - I should be given the option to overwrite the target display if I am the owner of both displays. I think having the warning message 'display already exists' is helpful, however, I should be able to proceed with the overwrite/save. If want to stage an update to a display in a limited access folder before copying the update to a public folder I am unable to do so - without having to create a new display in the public folder; I can shuffle names around(rename the old display to _old) in the public folder but any time a new display is created it get assigned a new display id, so if I had users with links to the old version of the display - I would break their links.
