Well, it does depend on how your adaptation is set up.
However, as far as I know, the Heading and Alt pop-up box is the same (i.e. you can't use one for easterlies, and a different one for westerlies etc) across the board.
We've only got room for quick buttons for I think five different altitudes, and four different headings, perhaps less. There's also a quick button for 'Straight Ahead'. If you want anymore than that, then the box will be getting so big as to cover the strips too much. So if you want any headings that are not covered by the quick button you will have to type it in using the keypad pop-up.
