Move photos to new folder on different disk, is there an easy way to do this?

I want to move photos to a new folder on a different disk, located deep down in that disk's folder structure. Since Lightroom won't work with Apple's Open/Save dialog for me to point it to a place to move photos, and Lightroom won't add an empty folder to the left side bar, I can see only two ways to do this.

1) Start at the top of the disk and work my way down "creating" folders, making sure that I use the exact name that that the folder already has. (Lightroom uses the existing folder if the name matches, otherwise creates a new folder).

2) Put a single photo in the folder I want to move to and then import that folder, in order to get the folder into the side bar, then delete that photo, then move the photos into the now-empty folder.

I use Lightroom to manage metadata that isn't written into the file (flagged status, custom metadata), so I can't move the files in the Finder and then import them, as I will lose all the data that isn't saved in the files.

Both 1 and 2 seem unnecessarily complicated, but I can't think of a third way to accomplish my goal.
