Chaning "All-In-One Center" Default Settings

Aaaargh! I'm trying to set up a Dell 968 All-In-One, but the scanning setup is driving me crazy. All I want is to scan documents or photos, and have a simple dialogue about what format I want to save them in and where I want to save them. And I'd like some basic defaults in place, like having the system save images as "date.pdf" in a "scans" folder designated by me.

Instead, there's nowhere in the All In One Center application for me to set a default save directory.

And even if I instruct the printer to "save file" rather than "email," the only option I'm given on the computer is to attach the result to an email.

The only way I was able to save a .pdf of my scan was to go along for the ride, attach it to an email, open the email attachments directory, then copy the file to the "scans" folder where I want it.

Is there a REAL, grown-up Advanced Settings somewhere that has this? Or is there a way to bypass Dell's poor software and use something else (for instance, CanoScan, which works nicely with our other scanner)?

Thanks for any help.
