You need to leverage the "PUT hook", described in the fishbowl at:

  http://dev.zope.org/Wikis/DevSite/Proposals/HookablePUTCreation

Basically, the hook allows you to write a PythonScript (or
ExternalMethod) 'PUT_factory', to override the default machinery
which tries to figure out the kind of object to make when an
FTP/HTTP PUT is done to a non-existent object.

Sample External Method::

    #Implement the "hookable PUT" hook.
    import re, OFS.DTMLMethod

    TEXT_PATTERN = re.compile( '^text/.*$' )

    def PUT_factory( self, name, typ, body ):
        """
        """
        if TEXT_PATTERN.match( typ ):
            return OFS.DTMLMethod.DTMLMethod( '', __name__=name )
        return None
