Like in page history there is option "Restore this version". Could same be used in attachments too? If I have for example 5 versions of attachment.docx and versions 4 and 5 were created in parallel and changes in version 4 are huge and version 5 contain only some minor changes (based on version 3). In that case I would like to "revert" back to version 4 (it would become version 6) and use that as a base for future changes.

I can do that manually now by opening version 4 and reuploading it as version 6, but could same be just automatized by "Restore this version" feature just like in page history?
