How to Refresh Subsonic Movie Library

I have moved movies I had added to iTunes on the Mac I use as the server from Home Movies to Movies. But when I use any client software or the Web interface for Subsonic, the changes are not reflected there. Is there a way to force Subsonic to update from the server? I notice a setting to have Subonic scan the media folders, but the shortest time available is "every day" at a chosen hour. Is it possible to force Subsonic to check for changes in the server on demand?
