Unfortunately I am fairly certain this is controlled by the operating system directly. Vectorworks can not control it on its own, since the most granular you can make this control on Mac is via the extension, which has been .VWX for all versions since 2008.
I will submit this wish but I believe it is not possible outside of something implemented by Microsoft/Apple.
However a trick you can use to see what version of Vectorworks a file was made in (iof you need this info in the future) is to open it in TextEdit or Notepad, it will tell you the version/build it was made in originally and the last version it was saved in as well, near the top.
