Allow Argo Server to aggregate workflows across multiple instanceIDs

[gyanprakash48]

When running multiple Workflow Controller deployments with different instanceID values (for load distribution), is it possible to have single Argo Server  that shows workflows from all instance id . I tired this but seems  like, server is supporting  one to one only.

1. When i started argo server without  instance id , it was showing only those workflows without any instance id
2. when i  attached a single instance id , it was showing workflows for that specific instance id
3. i did not find a way to attach list of instance id in argo sever config or argument  or e.g a wild card *

Is something like this possible ?  (if not already , via a feature request)

My use case is: i want to  utilise instance id to handle the large scale of workflows(as vertical scaling of single controller hitting the limit), but still i want to use central UI that shows all workflows
