Can I get Virtualmin script installer to recognize/update a manually installed script package?

Because of earlier hassles with using the script installer (related to the moving/rearranging of servers and subservers, it seems), I got gun-shy and manually installed a couple of scripts - WordPress, Gallery, Zen Cart - in a couple of otherwise unaffected servers (using the same installation packages as were available via Virtualmin). Now updates are available, in particular for WordPress; is there any way - a file I can edit, perhaps - to have Virtualmin recognize my manual installs in the same way it recognizes installs done by Virtualmin so that I can use the update process on those packages?
