Has anyone learned to switch genders deliberately?

Are there any techniques you use to feel femme or masc when you want? I don't like the uncertainty and dysphoria I suddenly get. I wish I could switch at appropriate times. For example, at work I'm more comfortable being a man, because I am more more rational and I am more respected as a man than if I presented as a trans woman. However, in situations when I need to connect with people on an emotional level, I do a lot better as a woman. My male persona is cold. I wish I could learn to switch genders as I want or even integrate them into one nonbinary gender.
