Independent Speeds for Mouse and Touchpad?

Hello,

I have a Dell Inspiron E1505 with Windows XP Media Center Edition. I tend to
alternate between using the touchpad and a mouse (Microsoft Notebook Optical
Mouse 3000). I can only find one setting (in the "mouse" category of the
control panel) to control the speeds (sensitivity) of those devices.
Unfortunately, I feel that when the mouse is at a comfortable speed setting,
the touchpad is too slow; and when the touchpad is well tuned, the mouse is
too fast. I keep having to go back to the control panel to change the setting
from one to the other...

Is there any way to independently control the sensitivity settings of each
device? I appreciate any help.

Thanks, JK
