I can actually see in the code that i deliberately omitted this option at the time.
That said, I cannot really recall why and con only think of either there being some security implications of some sort (which of course there are) or I got sidetracked with something else and never finished it off, leaving it until someone asks for it
– i.e now

let me see what I can do in the next update – it’s not quite as trivial as one would want it to be though unfortunately.
