We have pushed an update which now allows properties to provide quotes (This is the first release). Adding a quote will temporally hold the room for a period and auto cancel if the quote is not converted into a booking. 

You should see a new 'Add Quote' button at the bottom of the Add Reservation tab. 

You have the option to hold the quote for 24 hours, 3,5 or 7 days. If the quote is not confirmed at the end of the chosen period the quote will expire and the room released back for sale. 

You can view all your active quotes in Reservations > Reservations List > Active Quotes.
