Allow params / variables to be scoped per request

I would like to be able to use params or variables scoped to a single request. Maybe this is already possible, but I can’t seem to work it out.

I like to use request variables as I find it easier to quickly change a variable, rather than directly changing the json body. A use case might be that I have a resource-id defined in a environment, and defined as a request variable (can be enabled / disabled). In this case, priority should be 1 - request variable, 2 - environment.

A work around is using environments, but i often have use cases where it wouldn’t make sense to define all my variables in a environment as it would get long and unwieldy.

See this implementation in hopscotch as an example.
