Keeping subs/functions "collapsed"

Hi everyone

This is a very OCD'ish kind of question, but I was wondering if its is possible to keep subs/functions collapsed after you hit ok in the editor, because when ever I collapse my functions/subs and hit ok they "uncollapse" them selves the next time I open the editor.

This is a small thing that I would like to know, because it gives a very good overview of your work. It should be said that I am currently dealing with a code with several subs/functions and the code is approaching 1500 lines, so to find your way around is some times dificult. 

I hope that a kind soul will take there time to answer this unimportant question.

thank you
