Two different REST endpoints for each environment - how to handle this?

Hi, 

I am using Ready API 1.5.0 SOAPUING. 

For each enviroment, I do have two different REST endpoints. When I set up the environment, I can only give one endpoint for REST. How to give two different endpoints for same environment? Even if I set second endpoint through property, it won't work when I change the environment. 

Please see an example below:

Environment A : has two different endpoints - C and D

Environment B : has two different endpoints - X and Y. 

Thanks.m
