GCP dynamic https proxy/loadbalancer based on variable

Question

Using Google Cloud GCP I would like to achieve this kind of dynamic redirect:

https://my.domain/$variable -> instance from instance group $variable

https://my.domain/instance-group-name -> instance from instance group "instance-group-name"

Is this possible?

I know I could create a LoadBalancer and add UrlMaps dynamically for every path, but adding a new UrlMap takes like 8 minutes to have effect and I need this to be close to instant.

This feature doesn't exists yet. There is something very similar of what you expect in the serverless neg configuration named URL Mask. If you can move your workloads to Cloud Run for example, you will be able to leverage of this feature.
