Parallel test running

[KEC79]

Hia,
Apologies for the beginner question but is there a way to run multiple scenarios in a single test without having all scenarios defined in a single .yaml script?

The use case I am describing is that our product has approx 20 users journeys and we want to simulate realistic user traffic so need to have a test where users are going through all these journeys simultaneously but with weighting. As you can imagine 20 scenarios in a single yaml file is a lot so wondered if there was an alternative way to do this? For example break scenarios into their own separate files.

I have seen that artillery pro allows you to run 10+ tests in parallel - would this be a way around it? i.e. have 1 test per journey? But how would that work with weighting?

Thanks
