Listening to COM1 & COM2 Concurrenlty with Collins Avionics Panel

[flyboy114 4]

Hello.  I've got the Carenado Premier installed.  I admit it's one of my favorite aircraft to P3D fly.  I enjoy flying on PilotEdge.  I use the stock Carenado Proline 21 avionics (no avionics ad-ons).   As in other aircraft I'd like to be able to listen to COM1 and COM2 at the same time, but, haven't been able to figure out how to do this in the Premier (or any other aircraft with the standard Proline 21 panel).  I can toggle between COM1 and COM2 using the manual switch on the left pilot side panel, however, I'm unable to figure out how to listen to both frequencies concurrently.  

For example, when flying Carenado's C172 G1000 I can select the COM1/COM2 button on the Garmin audio panel and listen to ATC on COM1 and pick up an ATIS on COM2 at the same time.

Is there a way to do this (listen to both frequencies at the same time) in the Premier with the stock Collins Proline avionics and panel?

Thanks in advance for your reply!
