I'm writing to several parts/nodes of my Firebase database in one update. Is it possible to set the priority of a node when doing this? Example:

```
firebaseRef.update([
    "/some/node/": "value",
    "/some/other/node": "other value"
])

```

What if I want to set the priority of the node at "/some/other/node" at the same time. Is that possible? Something like:

```
firebaseRef.update([
    "/some/node/": "value",
    "/some/other/node": {
        value: "other value",
        priority:  0 - Date.now()
    }
])

```
