In my meteor app I'm using Session to store temporary info about user activity. I'd like to persist some parts of this info to the browser with amplify.js, but not all of it. 

I'd like a way to have 'temporary' Session keys and 'persistent' Session keys. Eg I could call 

```
Session.set('persistent', 'this is persisted to browser memory');
Session.set('temporary', 'this will be erased on page reload, etc');

```

and then after a page reload 

```
Session.get('persistent'); // returns 'this is persisted to browser memory'
Session.get('temporary'); // returns undefined

```

I found [a related post on SO](https://stackoverflow.com/a/14659101/1094784) but this saves this approach persists the entire Session object, which I don't want to do. Also, I don't want to use MongoDB for this, I'd like the storage to be purely client side...

Many thanks in advance!
