Hello everyone, to the initial question: yes, it is possible. @Drdpro16: It's even easier. You can go to Microwave, confirm the number of watts and then specify the time you want. I think you can turn it down as much as you want - even 5 to 10 seconds.
30 seconds, you can press start and the 30 seconds count down and between 25 and 20 seconds you just open the door and then you have your 5-10 seconds. That's what all parents do, including me. All the best with your first child.
