How to retrieve the return of the setup function

[blixit]

Hello

I'm working on a script to automate the generation of a JS script from HAR, the data injection and the JS script execution.

I want my JS script to contain a main function and a setup function such as:

export function setup() {
  let vars = {};
  // read a csv file that contains my dataset
  // update vars with data
  return vars;
}

export default function main(vars) {
  const randomIndex = ...; // computed from vars and the strategy
  const username = vars[randomIndex].username;
 
  group(...)
}

My current approach is to edit the JS file with another script that adds manually the wanted lines.

Is there a way to update the HAR in order to get this structure by running har-to-k6 ?

(If it's not implemented yet, just give me the recipe, I'll try a fork and submit a PR if the result is interesting)
