I'm not 100% sure what you are trying to do but I think what you want can be achieved if you use some kind of Assign app. I think MCP allows for this.
I'm also not sure why you don't put some assign commands in the user startup. Cli has to open up before workbench starts After workbench has loaded cli is not needed hence the endcli at the end. Without this you would have the shell window on top of your workbench screen
