Forum OpenACS Development: Re-directing in file-storage across versions

(I originally posted this question on IRC#openacs. I've posted here to add the follow-up questions and findings)

Here was the problem:
Our association mass distributed a link to a file in a v4.6.2 file-storage instance on our 4.6.3 OpenACS site. The  URL was of the form:
www.mysite.org/myfiles/download/index?version_id=2222

Subsequently, the editors found an error in this file. We needed to post the new version, and re-point any links to the new version.

Uploading a new version of the file within the file-storage instance created a new version_id (3333).

The links on our site were changed. But what about all those links that were sent with "verion_id=2222" ?

Could can I upload a new version, but keep (or force) the same version_id?

Or, alternatively: could I get version_id 2222 to point to version_id 3333
