Different Versions in ODF

In newer versions of ODF, can you add the option of saving multiple
versions of the same file in the same file, so ODF users can roll-back
to any saved version without losing a separate file?  I think this would
be handy, since I wouldn't have to always be using the "Save As" button
to make another separate file for all my different versions.  I could
instead just save the separate versions in the same file name, and then
could decide which to open when I open the file.
