Visual Studio - Is there simple way to add 'Close Solution" to r-click in Solution Explorer

In Visual Studio 2010 you can:

1. Right click on the Tool menu and click "Customize..".
2. Click the "Commands" tab.
3. Click the "Context menu" option.
4. Select the "Project and Solution Context Menus | Solution".
5. Click the "Add Command..." button.
6. Select "File" in the "Categories" list box.
7. Select "Close Solution" in the "Commands" list box.
8. Move up/down as desired.
9. Click "Close" and enjoy.

I don't have VS 2008 or 2012 handy, but the steps should be similar.

Edit: For VS2008

1. Right click on the Tool menu and click "Customize..".
2. Click the "Toolbars" tab.
3. Check the "Context menu" option. (the Context Menus tool bar will appear)
4. Select Command Tab in the current dialog.
5. Select "File" in the "Categories" list box.
6. Select "Close Solution" in the "Commands" list box.
7. Drag the Command to the "Select the "Project and Solution Context Menus" in the context Menus toolbar. You can drop it anywhere on the menu or in a sub menu - ie "Project and Solution Context Menus | Solution"
8. Click "Close" and enjoy.
