PC Spotify Connect and Linked Accounts

[z00maz00m]

I use Spotify on a PC to connect to a number of speakers spread throughout my home.  I then drive my music selection through Spotify Connect on my iPhone.

My wife has been added as a Linked Account.  I would like my wife to be able to use the Spotify on her phone to Spotify Connect to my PC at the same time I am.  This would enable us to generate a shared Queue where both her and I could contribute.

Is this possible?  It appears to be locked to only one account, or the primary.

Thanks,

Dave
