Open a specific tool in a specific custom toolbox

Running V8i Rev 10

I read the tip on opening a custom tool box with a keyIn and it works great. I was hoping to go 1 step further

can you open a tool itself that is in a custom Toolbox.  

Previous Tips: 

Key-in: dialog toolbox <toolbox name>  or Key-in: dialog toolbox "toolbox name"  Works on custom tool boxes
