System Preferences as a stack

Question

I've made a stack of all the system preferences by dragging the PreferencePanes folder to the dock. This makes a nice quick way to access system preference items.
Here's the problem:
Instead of showing the icons for the preference items, the stack shows a page with a gear on it with the icon for the item inside the gear. If you do a Get Info on the item in the PreferencePanes folder, it shows that the icon in the stack that I don't want is the preview icon for that app.
So, how do I get the stack to not show the preview icon, or how do I change the preview icon?
Thanks!

Answer 1

You could create an application item named MY_SYSDATE (for example), then create a before-header computation of type PL/SQL Function Body that does
return to_char(sysdate,'MM/DD/YYYY HH24:MI:SS')
or in any format you like. This will recompute your item MY_SYSDATE on each page view. Then in your template reference &MY_SYSDATE. (note trailing period).
