When create a new version of a sheet from PDF Setting.
We need to match a page# and a discipline to be able to select the previous version.
In large building, our criteria are more: Location, Sub-Location, Area, sib-Area then then discipline etc...
Also, the document name should be one of the criteria ↑ as the new version of a sheet will come form a document having the same name or the same Document Number If the Document Number match then most likely all other criteria will be matching or can be retrieve/populate from previous version.
