Confusion yet again
 

So far I have been playing Quick Missions and Single Patrols and using a "Custom" Options Choice with some of the difficulties selected and some not.
Today I started to play my first Career game but within this ,the Difficulty Level Choices do not seem to allow a "Custom" selection--only Low,Medium and High etc.
Is this actually the case ?
Being able to precisely tailor the range of difficulty options to ones own needs was for me one of the major advantages of this sim---but if this is not possible in the central Career mode that rather ruins the sim for me.
Could anyone please confirm whether I have understood this rightly or wrongly and if wrongly---how and where can one Customize ones Career Difficulty Level.
Many thanks for any help on this

In the office before you start your career you change your option in there for your game. I believe it is in the bookshelf to the left.

That's right:yep:

Thanks guys----you need eyes like a hawk to play this sim..........
