multi-level app-of-app with sync wave not honoring the order

[thirumurthis]

In ArgoCD v 2.14.21 using multi-layer apps-of-app pattern with sync wave to deploy apps to cluster. The argocd cm is updated with application health check custom code.

The app-of-app with sync wave looks like below. The number in () is the sync wave number

   app-parent 
        |________leve11 child1 (2) 
        |________leve11 child2 (4)
        |________leve11 child3 (6) *[parent]
				  |________leve12 child3.1 (6)
				  |________leve12 child3.2 (10)
				  |________leve12 child3.3 (14)
				  |________leve12 child3.4 (18)
				  |________leve12 child3.9 (38)
        |________leve11 child5 (50)
        |________leve11 child6 (55)

When we configure the git repo and sync for the first time, we do see that all the app in "level1" is getting synced based on the order.
Noticed that the level1 child5 is not waiting for the level1 child4 children apps to completed, could see the level2 child apps are still synchronizing, but the level1 apps are completed sync.

The order is added since the level1 child5 needs the level2 child4 apps to be deployed.

Question - is there a way to configure argocd to follow the sync order strictly even at the child level app-of-apps?

The demo code is updated in git-repo.

I had to add health check code like below in argocd-cm config map. This seem to wait for the child apps to do. But not sure whether this is the correct approach. The manual sync is indicates the application with child apps and level1 apps are syncing very quickly.

resource.customizations.health.argoproj.io_Application: |
    hs = {}
    hs.status = "Progressing"
    hs.message = "Waiting for child application to be ready"

    if obj.status == nil then
      return hs
    end

    -- If sync is still running
    if obj.status.operationState ~= nil then
      if obj.status.operationState.phase == "Running" then
        hs.status = "Progressing"
        hs.message = "Child application sync in progress"
        return hs
      end

      if obj.status.operationState.phase == "Failed" then
        hs.status = "Degraded"
        hs.message = "Child application sync failed"
        return hs
      end
    end

    -- Check sync status
    if obj.status.sync ~= nil then
      if obj.status.sync.status ~= "Synced" then
        hs.status = "Progressing"
        hs.message = "Child application not synced"
        return hs
      end
    end

    -- Check health status
    if obj.status.health ~= nil then
      if obj.status.health.status == "Healthy" then
        hs.status = "Healthy"
        hs.message = "Child application synced and healthy"
        return hs
      end

      if obj.status.health.status == "Degraded" then
        hs.status = "Degraded"
        hs.message = obj.status.health.message or "Child application degraded"
        return hs
      end
    end
    return hs
