Proper and equal is easy. I have a bamboo skewer in the garage with tape around it I use as a refill marker. Do it properly once, measure and mark it once with the front fully down and the springs poking out.

Next time loosen the top clamp bolts, undo the caps, push the front of the bike down, pump the oil out that you can get at from the top (~2/3) (my forks don't have lower drain holes) and refill with fresh to the mark. Put it back together.

5 minutes every six months is a LOT less effort than several hours every two years, and I'll bet on average my oil is in better condition than yours. It's not engine oil (where this would be a bad idea) it ages totally differently.
