LocalRateLimiter with dynamic descriptor values

I have setup a localRateLimiter Filter on the route level . I am trying to configure the rateLimiter such that the limits are applied based on the remote-address or an Auth token passed in the request header. Eg: For a particular API path /foo, Allow 5 reqs per min per token or remoteAddress. Although I could configure this with the GlobalRateLimiter, despite digging through the documentation multiple times, I am not able to find a relevant configuration to achieve this with the localRateLimiter.

LocalRateLimitConfig

       route:
          rate_limits:
            - actions:
                - request_headers:

Using the following struct provided for the globalRateLimiter Config throws an invalid descriptor error.

Does Envoy not support dynamic values for LocalRateLimiter descriptors .. ??
