Custom edit command. Possible ?

I need to edit config file, always stored at the same location on remote machine, and I want to create custom command for this task.
It should work the same way, as double click on the filename in browser window.

Does somebody know syntax for this command ?
Is it possible ?


WinSCP ver. 4.3.5

Not possible yet.
