Routing traffic to Chaos testing config

I’m reading traffic management documentation Istio / Traffic Management and also use istio for chaos testing Istio Chaos Engineering: I Meant to Do That | Red Hat Developer

I know we can use some headers value to routing traffic for A B testing, but what I would like to know, is if I can do the same to return an error in one service or make a delay, as the istio chaos testing provide.

So I can end up making request with header request-type:chaos, and for those we will apply the chaos testing yaml config, but not for the rest of request
