Making Unity .desktop files to have different left click and right click actions

Question

I'm trying to make a custom google chrome .desktop file to have all of my favorite websites just a click away. This is what I have so far :

    [Desktop Entry]
    Version=1.0
    Name=Google Chrome
    GenericName=Web Browser
    X-GNOME-FullName=Google Chrome
    Comment=Web browser from Google

    [Desktop Action Chrome]

    Exec=/opt/google/chrome/google-chrome

    [Desktop Action Incognito]
    Name=Incognito Mode
    Exec=/opt/google/chrome/google-chrome --incognito

    [Desktop Action Separator]
    Name=*****************
    Exec=

    [Desktop Action GooglePlayMusic]
    Name=Google Play Music
    Exec=/opt/google/chrome/google-chrome --app="https://play.google.com/music/listen#start_pl"

    [Desktop Action Drive]

    [Desktop Action AOLMAIL]

    [Desktop Action UbuntuOne]
    Name=Ubuntu One
    Exec=/opt/google/chrome/google-chrome https://one.ubuntu.com

    [Desktop Action Youtube]
    Name=Youtube
    Exec=/opt/google/chrome/google-chrome http://www.youtube.com

    [Desktop Action Separator2]
    Name=*****************
    Exec=

    [Desktop Action GoogleReader]
    Name=Google Reader
    Exec=/opt/google/chrome/google-chrome "http://www.google.com/reader/view/#overview-page"

    [Desktop Action MyWebsite]
    Name=My Website
    Exec=/opt/google/chrome/google-chrome --app=http://tylorsteinberger.jumpingcrab.com

What I'm really wondering though is if it is possible for me to say "left-click" on say "Google Play Music" and open it regularly and to "right-click" on the same link and open it in incognito mode.

In other words can I assign something like 'onleftclick' 'onrightclick' to each entry in some sort of way or is this impossible at this point in time?

If it's impossible does anyone know where I could go to make this type of suggestion to be added to functionality in later releases of Ubuntu or gnome or wherever this issue could be resolved?

Thank you very much in advance any feedback will be greatly appreciated.
