PLT Default Print-To Directory

I know that I can force Microstation to print to a certain filename / location with:

default_outFile /auto_overwrite = "C:\TEMP\$(basename(_DGNFILE)).pdf"

But what if I want the printer icon to open to a specific folder and then allow me to name the file?

Could I use the same : default_outFiel/auto_overwrite and just leave out the file name? Or does that screw things up?
