Hello, is there a way that we can just select the first value of that new Join parameter? E.g: I wanted to output that Join parameter that looks like this "abcd-us-east-1-stackname", if I want to reference (in a different stack) just "abcd", and then in a different variable "us-east-1", how should I do that? Thanks.
