Multiple Named Queues

Has there been any thought into having multiple named queues, instead of just one queue as it exist today? My use case is that I have 2 sections on the page for flash type notifications...eventually there may be 3. Ideally, I would like to use this exact same component for all of them, the hbs code would simply loop over a different queue, i.e.:

```
{{#each flashMessages.queueFoo as |flash|}}
{{! flash from queue named foo}}
{{/each}}

{{#each flashMessages.queueBar as |flash|}}
{{! flash from queue named bar}}
{{/each}}
```

If there has not been any previous discussion on this...any thoughts on doing this? I would be happy to do the work and submit a pull request, but first I wanted to see if this has been previously discussed.
