Thanks for re-visiting this, as I had completely missed on how to change this default behavior since X2a. Now I can see my stereo/mono UAD plug-ins clearly defined again. 
 
Cheers,

Hi Billy,
 
Yeah, my UAD and NI plugs are the main reason I was looking for this.  Most others it doesn't make a difference, but between the mono vs stereo on the UA's and the various versions with different numbers of outputs on the NI synths and FX's I really needed to figure out how to turn the DLL name back on.  As always scook came to the rescue with his nearly encyclopedic knowledge of Sonar!  I didn't even know how to ask the right question which is why I didn't find anything when I searched.
 
Cheers!
