site wide default album thumbnail

I don't necessarily want an image from within the album to be the thumbnail for the album and I don't want to upload custom thumbnails for each album.
Can I set up a generic thumbnail to be used a default for all albums?

A little background:

I'd like to use gallery as a repository of photos related to building improvements.
Every project will have its own album. Every building within each project will have its own sub-album and every building sub-album will have a "before" sub-album and an "after" sub-album.

Confusing? It's simpler than it sounds.

When a building is added to the system, all the albums are pre-created using the gallery remote protocol. This works great, except that since the albums don't have any pictures in them yet, all you get is a "no thumbnail" link. Kind of ugly.

Then when you do add the first picture to a sub-album, it becomes the thumbnail for all the albums above it. This isn't the behavior I'd like.

I'd like to use generic thumbnails for the albums. Any new album that's created would automatically use the generic thumbnail without having to upload a custom one.

Alternatively, An icon in place of the link that says "No Thumbnail" would be just fine.

Possible?

Thanks !
