How to set canary traffic percentage?

[caibirdme]

Say, I have a HPA deployment, I want to upgrade it from v1 to v2, and I want to use canary strategy like this:

trafficRouting:
  nginx:
    xxx
steps:
- setWeight: 5
- puase: {}
- setWeight: 20
- puase: {} 
- ...

I want to know if there's a way to set the percentage of traffic to v2 at the same time? Like upgrade

- upgrade 5% pod
- give them 10% traffic
- pause: {}
- upgrade 20% pod
- give them 50% traffic
- ...

Have you seen "setCanaryScale"? See more at the docs https://argoproj.github.io/argo-rollouts/features/canary/#dynamic-canary-scale-with-traffic-routing

thanks for your reply @kostis-codefresh, but we found setCanaryScale doens't work with dynamicStableScale

I didn't know we have a github discussion section so I created a bug issue
