How do I setup my working Directory without using the pop-up?

Hello
Where do I configure APP Working Directory?
i.e. where is APP Configuration or Options or Preference Settings?
Silly question?
I have no idea if there is a way - strange if not there and I also searched here - maybe it is here and I did not find it.

I do not mean the pop-up 'Please select your working directory' thing, but a proper settings page.

It hurts my brain to see it every time, as we all have a different brain and different way of doing the same thing.

Thanks in advance

M
