Group Desktop Icons in Unity Launcher for similar program windows

view story

http://askubuntu.com – This a specific example of a generic problem I haven't been able to find a solution for yet. I have a program (Android Virtual Device Manager) that launches 'sub-programs' (namely emulators or virtual devices) from within itself (also can be launched from else where). I want any instances of EITHER of these programs to be grouped under the same Unity icon. I have created a .desktop file to try and accomplish this but don't exactly know how to go about it. The desktop file is as follows: #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Application Terminal=false Name=Android Virtual (HowTos)
