Print Organizer - where is the variable to select where to look for PSET

Or IS there a variable? EVERY time I try and open a pset I have to hunt down the folder under "Directory". I would like to at least see a directory on our server. Right now and ever since I stared using PO I have to look somewhere other than this folder on this computer

and while I'm here is there some way to make this dialog box larger so I can see the entire line(s)

Thank you
