Is it possible to change a scorecard setting from strokeplay to stableford after a round?

I played a competition last week and forgot to change the scorecard setting from strokeplay to stableford from the week before. Once I realised this, I carried on my scoring on the S62 rather than cancel the round, but when I got to a hole that I scored no points on, because I didn’t ‘hole out’, became a problem. 

Is it possible to change the scorecard setting after the round has been finished and been saved?

Thanks.
