Late availability 10 - 12 day window

I like the late availability tab and think its very handy to be able to see who has spaces, however its only for the 3 nights over 3 weekends (by then its not late availability if you get my drift) I would like to see the next 10 or 12 days availability if it was possible to do so. It would be very handy when out and about touring as you wouldn't have to phone around or spend ages checking each individual site to see it you can get more than the 3 nights. What are your views does anyone agree?  It would allow a little of the old way of flexable touring.
