For those with multiple properties and potentially multiple pricing levels a simple 3 character long column that would allow you to assign a property to a pricing tier would be helpful.
So for instance you have 20 rentals, 10 are level 1, 5 are level 2, and 5 are level 3
With a tier indicator the rate calendar could filter on that column to only display properties from a specific pricing level which would be very helpful when making rate modifications.
Or, imagine if it was possible to choose and say that 1) property A's rates are the same as Property B's 2) property A's rates are x% lower or higher than Property B's 3) property A's rates are B's prices -+10
If this was possible, potentially you could define rates for 1 property and maintain rates for 10,20,30 ... properties.
