Room available calendar for multipal hotel!

[rrh]

Need help!

My existing version is Elxis IOSR 3.6 with 2009.3 for online hotel reservation!

Is it possible to set the date of room available calendar for multipal hotel instead of individual?
Because most hotel doesn't want to accept last minutes booking and ask us to send one week advance.

Currently I need to change the room avabilities for every room for every hotel daily. (please see sample attached!)
