This is only an issue if you are tankering fuel as it sounds like you are talking about.
In this instance most people will look at the second or last sector "fuel required" then add the burn, taxi, and a little extra from the first/second/etc sectors. I don't know which CFP sytem you use so can't comment on its format.
Put simply, you can't depart on any sector with less than required fuel . First sector is no problem as you are way over, departing on the last sector with required fuel is the trick and experience will help you achieve this.
I don't see your problem.
Also, 200 kgs seems a little high for taxi fuel, we use just over half this.
