On jets don’t dive and drive, at least not in EASA land. Extend it outwards and upwards as mentioned before. It is not that hard. If you have profile or vnav all you need to do is monitor if you haven’t you add 1 mile for every 300’ and asjust ROD when needed. It really doesn’t matter if you do it in Profile and nav or hdg sel and v/s, as long as you do it correct
