I hear what you're saying, but I just think it would slow down the gameplay too much. You could always set up different strategies for each preference, and switch to the one you want during the match. For example, if you see that your team is struggling in lineouts but has dominance in the scrums, you could switch during the game to the strategy where you have your preference for penalties set to scrums. So I think having a preference setting in the strategy menu would be easiest and have the least impact on gameplay
