Nope. You have to run the Wave Shell.
I would have to personally move each Wave Shell one by one and load up my DAW a bunch of times to find out which one had the API Plugins. It's a bitch.
If your installing the Mercury Bundle, you have to completely uninstall everything Waves Related first, and then do a clean install of Waves Mercury.
This includes deleting any and all Registry Entries of Waves, everything.
I hate the Wave Shells also. Because, when I first installed the Mercury Bundle, every Plugin was duplicated in my PT 7.4. I had to go through each Wave Shell in my DAE\Plug-Ins folder and delete/move one until I found out which one was duplicating my Waves Plugins, because each plugin was duplicated. I had 2 Mono's and 2 Stereo Plugins for each Plugin. I finally found out which Wave Shell it was, I wrote it down to a Read Me file and backed it up incase I ever installed it on another machine or whatever. And then I deleted the corrupted/duplicated Waveshell.
You just have to install them, and then if you want to find out what is in what, you have to move a Waveshell, re-load your DAW, see what show's up, move it back, move another one, etc. And then make note of it.
