Yes, this has come across the list before. The easiest thing to do is
just delete/recreate the tag.

svn delete url://server/repos/tags/productname_CURRENT -m "Refreshing tag"
svn copy url://server/repos/trunk
url://server/repos/tags/productname_CURRENT -m "Refreshing tag"

As you indicate it is the same feature with a different implementation. I
personally prefer the Subversion approach in that there is no need to
really introduce a special UI or concept for a feature that can already be
accompished. There is a consistency that is really easy to follow once
you grasp it and can set aside what you are used to from other tools.
