Incorrect style of writing logs

Incorrect style of writing logs
```
 _logger.LogDebug("Starting step {0} on workflow {1}", step.Name, workflow.Id);
 _logger.LogError(ex, "Workflow {0} raised error on step {1} Message: {2}", workflow.Id, pointer.StepId, ex.Message);
```
I have some problems with fields 1 2 3 

Can I or someone change the names to strings ? Somethings like workflowId StepId and Message
