How to create new userProperty based on existing properties?

Let’s say I’ve got two user properties for my user. Those are “Gender” and “Age”. Both of those properties are created the moment a user is created with an event “Init”. Lets say, that right now I want to create another userPropery based on those two events. That will be targetGroup and the value is based on Gender and Age. If Gender = male and Age is more than 20 and less than 30 than targetGroup = true. Oherwise it’s false. And if gender = female and Age is more than 20 and less than 40 than targetGroup = true. Otherwise, it’s false.

Is this possible with Amplitude? How to do that?
