Serverless If Else Plugin

I am very new to serverless.
I just want to know if there is any way around that we can create s3 buckets using serverless if else plugin.

What I am trying to achieve is that I want to create new s3 buckets as per Stage I gave in if else statement.

Fr example if script(serverless.yml) runs in production stage it should create different s3 bucket and if script runs in development stage then it should create different bucket according to if else statement.

Please let me know if there is any way around to achieve this.
