Need Intellisense for templatespec references

[neok-g]

I have added 2 module aliases in bicep.config like shown below:

    "ts": {
      "specs": {
        "subscription": "subscriptionid-prd",
        "resourceGroup": "rg-templatespecs-prd-001"
      },
      "specs-nonprd": {
        ""subscription": "subscriptionid-non",
        "resourceGroup": "rg-templatespecs-nonprd-001"
      }
    }
  }

The resourcegroup for alias specs-nonprd contains 3 templatespecs:

The intelissense is working for the alias part see below:

However if the alias is entered intellissense does not work for the 3 templatespecs nor for their versions:

Is this by design or a known issue?

Expected behavior would be similar as with Azure resources:

We currently have no implementation for template spec completions except for the top-level aliases as author points out.
