Good tool for placing 3rd party/addon scenery objects in FSX?

Pretty much as the title says, I'm looking for a utility to place objects in FSX. I'm not placing any default objects, they're all 3rd party objects from the addon scenery folders. Ideally it would allow seeing what an object looks like, and finding it by name, (or which .bgl), since I can't get a GUID/object relationship for everything I'd like to place. (Some of them are fs2004 objects that model converter X can't read.) The default object placement tool isn't really going to work.

So, what are some tools/utilities that would be useful?

Thanks.
