Auto Dutchbetting and Saving on selections

Love the autodutch feature in MF. I would love to see it possible to be able to BACK a certain number of runners and have the option to SAVE on any number of runners.

eg. BACK the favourite to make a profit but then SAVE on the 2nd and 3rd favourites so if they happen to win you get all your money back that you invested on the race.

This might be a tough one to implement but I'd love to see this too.
