How to have default "Filenames Pattern" in Search Files in IDE

When I open Search Files in the LWW6 IDE, I'd like "Filenames Pattern" 
to default to something - either the last path and filter I used or one 
that I can specify in a preference.

It looks like there is something related in Preferences..Search 
Files..Search Parameters..Pattern, but after entering, for example, 
"*.lisp" there, I still have a blank input box in Search Files. I also 
don't see anything happen if I create an include list in the Search 
Files..File Types tab.
