[GNC] Automatic Price Updates

[rsbrux]

I used to have a chron job set up to automatically fetch security prices 
on first login each day, but found this inconvenient because it locks 
the data file, and opening GnuCash is often the first thing I do upon 
logging in.

I have noticed that when I have GC open interactively, I can start an 
update in the price database window and let it run in the background 
while I continue to work in the registers.

Would there be some way to get GC to perform the Price Database 
automatically when GC is started (interactively), instead of performing 
the automatic price update in a separate session?
