Change Session icon on Vpn connect

Hi all!
Here's my issue/requirement.

• I have a "VPN/tunnel/gateway - Custom VPN (PowerShell)" session entry used to create an L2tp/Ipsec on windows client
• when I click on the RDM session it creates the VPN and connects correctly
• once connected I don't see the session icon change on RDM, I guess there is no iteration

Once the VPN is connected, I'd like to change the session icon so it's clear it's being used, for example, changing the color to green until the session is closed.

Is this possible?
Please help!
Thanks!

Stefano
