Option to confirm if you want to use gold bars to finish a level

I have lost most of my gold bars by my mouse accidentally tapping the Play On with gold bars option after the last move of a level not completed. I'm sure you won't add these back to me. But could you add a button to confirm the use of these the same way you have the button to Play on with bars. This will help us a lot as I know I'm not the only one with this problem.
