Hi @Jac,
As shown in Scenario config file - #2 by nedyalko you can load the config file as a normal file, parse it from JSON and then set it to export const options. You can also just before that change w/e options you want.
This also (as shown there) can be done only for some option keys - you don’t need to write the whole configuration, as needed for --config.
And you can use env variables to choose the “configuration file” an then what the replace for your needs.
Hope this helps you!
