Aux In and Bluetooth In at the same time?

[SPark's Finest]

Is it possible to use both the Aux-In AND the Bluetooth-In at the same time? I use my Spark as a monitor for my rig and want to be able to connect Bluetooth to practice over songs streamed from my phone. I used to be able to do this with the Vox Adio Air and thought it was possible with the Spark.

Now, when I have my rig plugged into the Aux In, it cuts the Bluetooth link. The only way to have the Bluetooth streaming audio is when nothing is plugged into the Aux In. It would be nice if both could be active at the same time.

I've read on the site that there is an established hierarchy for what connections have priority over the others, but I would like to know if it's possible to have multiple inputs in at the same time...
