Allow discount code to be flat rate

I love the discount code feature but am hoping you can easily add an option for a flat rate (instead of a dollar amount or percentage off). For example, I want to charge friends only $50 a night but the current discount code options will only let me do this if my rate is the same every night.

Yes we would also like this feature to be able to discount one free night on a stay. We have discounts that we run all the time when I guess books 3 nights or more or four nights or more they get a free night and it would be nice to be able to discount one night off instead of a single dollar amount or a percentage amount. Could be done very simply just average the nightly rates for the stay and discounted by that average.

I would also like the ability to discount one night stay.  

Me Too! Not that kind of Me Too. But Me too. lol

Yes! It would also be great for using with a Snowbird discount - eg: $2500 when they book for the whole month of January. 

Add to flat rate the ability to have a discount that can be a mix of dollar off and percent for one code.  For example; I offer returning guests discount based off of length of stay.  3 nights = $75, 4 nights = $100, 5 -11 nights 10%, 12+ = 15%. I'd like to send them one code that they can use to get the appropriate discount.

I would like the ability to offer a percentage discount on ONE night if stay is 3 nights.  So, stay Mon - Wed, with Wed being 50% off.  Not 50% off the Subtotal of rent.
