Accessing multiple network zones over IPSEC VPN

I am trying to setup a IPSEC tunnel between two PA-2020's, one on each side.  I have the tunnel connecting and can access devices over the tunnel. However I am trying to access multiple network zones over the tunnel, and I am not sure how to configure that.  I've typed up my setup below.

Site-A (main site) has a 192.x.x.x/16 and a 10.10.x.x/16 network.  Site-B (branch side) is a 10.20.x.x/16, 10.30.x.x/16, 10.40.x.x/16, etc networks separated by physical interfaces and zones. We have a tunnel bound to our 192.x.x.x/16 network that allows us access to the 10.20.x.x/16 network, and a route of 10.20.x.x/16 traffic destined to the tunnel. However I am a bit confused on how to get the 192.x.x.x/16 network traffic to route to any of the other networks, 10.30.x.x/16, 10.40.x.x/16 through the same tunnel, or over different tunnels.

Do I need to specify proxy-ID information in the tunnel for the connections to work?

This thread is similar in the line of questioning, but not quite what I am needing help with: Bind multiple VPNs to a single tunnel interface?

If there is any other information I can provide to help make this more clear, please let me know.  Thank

Figured out my problem.  Firewall policy rule on FW at Site-B needed to allow me to gain access.

I've setup a similar setup with two PAN's, do you have a tunnel interface network or only using the IKE to setup the tunnel? I only added the additional routes to the tunnel interface and it's working fine, if it's also allowed in the policy.

I'm using IKE to setup the tunnel, and then have a tunnel established in the second phase. If that makes sense?
