Route to replica on same node

Traefik Traefik v1

Hello!
I followed the Traefik Swarm tutorial from dockerswarm.rocks (https://dockerswarm.rocks/traefik/).

I have my Traefik proxies and my apps set as global deployments (1 proxy and 1 app per node).
However, my cluster lies in multiple zones for HA reasons (One node in SF, another in NYC and another in London).
The problem is that each Traefik proxy routes to any of the app backends, independently of whether they're hosted on the same node or 5000kms away.
I'd like Traefik to route to the app backend on the same node and possibly to the app backend on another node if the one on the same node is down. Is it possible to do so in a simple manner?

Here's my traefik config:

version: '3.3'

  consul-leader:
    image: consul
    command: agent -server -client=0.0.0.0 -bootstrap -ui
