Tom,
You can stop asking this question now.
We have given you the answer every time you have posted this same question.
What's it been now 6, 7 times since February?
The answer has not changed since then and it is not going to.
Just because you "want" to do something does not mean you are going to be
able to do it.
You have to deal with the limitations of the OS.
Also, please stop changing your return address.
Every time I add you to my kill file you keep showing up again.
