Local Tunnel port: Autoselect and Custom Command patterns

I am using winscp 5.7.5 on Windows 7 to multiple linux hosts through tunnels.
I want to use Local Tunnel port: Autoselect but I also use Custom commands a lot and need the autoselected local port and possibly the tunnel user and tunnel password. These don't appear to be available in the Custom Command Patterns. Please enhance and fix this. I have many hosts to support through multiple tunnels and and don't want to hard code ports for generalized scripts used in Custom Commands.

Thanks for your suggestion. Let's see if more users ask for this.
