Target backend based on path

[antedebaas]

I would like to be able to target a example.com to one backend and example.com/instance to a different backend.
eg:

[clusters.example]
protocol = "http"
https_redirect = true
sticky_session = true
frontends = [,
    { address = "0.0.0.0:443", hostname = "example.com", certificate = "cert.pem", key = "privkey.pem", certificate_chain = "chain.pem" },
    { address = "0.0.0.0:443", hostname = "example.com", path = "/instance", certificate = "cert.pem", key = "privkey.pem", certificate_chain = "chain.pem" }
]
backends  = [
    { address = "127.0.0.1:8001" , sticky_id = "backend1_1"}
    { address = "127.0.0.1:8002" , sticky_id = "backend1_2"}
    { address = "127.0.0.1:8011" , sticky_id = "backend2_1", for_path="/instance"}
    { address = "127.0.0.1:8012" , sticky_id = "backend2_2", for_path="/instance"}
]

currently i would have to create 2 clusters with the second one on an different host (eg instance.example.com)
