GE v6... has something called 'advanced reservations' which give you the 
functionality you want.  The documentation is available from the usual 
source.  We're intending to upgrade next month (yes, slow aren't we ?) 
in part to use this new feature.  I expect plenty of the other regulars 
on this list already have experience they could share.
