flex builder modules debugging

Shouldn't flex builder automatically enable debugging for modules when you fire up your app in debug mode?
in flex builder 2.01 i would just check the url and if there was a debug=true there i'd load the debug version of the module. simple and nice, now it seems everytime i want to debug something that's in a module I have to turn debugging for modules on, and then when i'm not running in debugging mode it generates errors.
