Azure linked ARM templates passing parameters from file vs inline problem

Question

We are working on linked azure ARM templates for our deployment.

The problem we are facing is if we choose to have different parameter files to link, like below, then we cannot use function in them.

linkedTemplateParameters.dev.json
linkedTemplateParameters.prod.json
linkedTemplateParameters.staging.json

for e.g. i can NOT do somethign like below in a parameter file

  "parameters": {
      "tenantId":  {
         "value": "[subscription().tenantId]"
      }
    }

so we have to hard-code them in the parameter files.

Now this might be bad in itself, but in cases where there is absolutely no way of giving a static value but need to dynamically fetch/generate it, that limits us to use parameter files altogether as we cannot mix passing parameters inline and via parameter files

Is there a way to pass dynamic parameter values still keeping the parameter files?
