Multiple functions submit dialog very cluttered when using lots of segments

[zaddach]

I like to add additional code I find during the analysis of a sample as additional segment to my code. Thus I can have > 10 segments in my database. In this case, the submit multiple functions dialog tries to display all segments on the vertical width of the window, and each scrollable list will show only one item. It is very cumbersome scrolling through each list one (visible) item at a time.
