How to add additional start parameter to a pinned prgm?

[msoff20xx]

Assume I pin a prgm to the Taskbar in Win7.

How can I (later) add some additional start cmdline parameters for the launch of this program?

Sample:

I pinned Windows Explorer. How can I add

explorer.exe /n,/e,D:\work

Do I really have to create a shortcut first, then add the parms here in shortcut Properties and finally pin the shortcut?

I cannot believe this cumbersome procedure should be the only way.

Under WinXP I could directly right click on an icon on QuickLaunchBar and add the parms without problems.

This is not possible in Win7 any more.
