No, and such an option will not be considered for implementation in the foreseeable future.
 
The reason for this is that DGS has a two-phase system for moves. A player makes a move and only submits the move if satisfied. If the player is not satisfied the player can retract the move and try different moves (as many as desired*) before submitting.
 
*The only constraint on the number of moves a player may try is that the clock will continue to run until a move is submitted.
