Custom dialogs like "Create new Test" in IntelliJ? Create class based on class?

Question

"Create new test" dialog in IntelliJ

automates creation of test classes. Test classes are autogenerated classes, bases on selected ones.

Can I create such dialog of template of my own?

I would like to create classes like this

public interface AddressRepo extends CrudRepository<Address, Long> {
}

where Address is the name of original class.
