If I'm following you correctly, this is Really Hard To Do in
Subversion. In SVN, a directory contains a particular version of a
file, not the abstract file. Every time a file or directory gets a
new revision, so does its containing directory. And therefore, *its*
containing directory. And so on. And so on. Clear back to the root
of the repository. This is intimately related to one of the SVN
trademark cool things: O(1) tags.

Looking over your remarks, you may also be assuming that all files
are within the same repository--notably, that all files use the same
conventions about where you copy things to. This is not necessarily
the case.
