Use different MS account with Smartglass

Is this possible? I have 2 MS Accounts, one I use for XBL (@Live.com) and the other for everything else including my PC @Gmail.com. I don't see an option to use my XBL Email, was curious if anyone else found it?

Have you tried going to your Microsoft Account and adding your Live Microsoft Account as an alias to your Gmail Microsoft Account?

This would maybe allow you the option to choose which microsoft account to use with Smartglass as they are now synonymous.

Make sure you set the account you want to use Smartglass with as your default alias.

You can still use both the accounts as normal, but this will allow you to use your other account to log in to the Microsoft Account you have set it to primary for.

Let me know if this works. I'll try and get back to you when I can.
