In Spring Boot, How to assign the exact same random port to another property in configure

I am running spring boot with grpc-spring-boot-starter as a grpc-server and also configured as an eureka client.

Since I'm trying to launch more instances later, i want to assign a random port for my grpc service so I made grpc.port=0

The problem is, I also want eureka.instance.nonSecurePort to be the exact same port as grpc.port.Here is my configure. 

grpc:
  port: 0

eureka:
  client:
    service-url:
      default-zone: http://localhost:8761/eureka
  application:
    name: grpc-service
  instance:
    securePortEnabled: false
    nonSecurePort: ${grpc.port}
    instance_id: ${spring.application.name}:${spring.application.instance_id:${random.value}}

The problem is, I always get eureka.instance.nonSecurePort to be 0 which is not what I want. I know the random port is assigned during runtime. However are there anyway to make the grpc.port and eureka.instance.nonSecurePort always the same after spring boot assigned the random port?

You can put random port following an interval by following way:

grpc:
  port: ${random.int[9000,9900]}

eureka:
  client:
    service-url:
      default-zone: http://localhost:8761/eureka
  application:
    name: grpc-service
  instance:
    securePortEnabled: false
    nonSecurePort: ${grpc.port}
