Hello there, 

When I plan a flight from A to C, with an intermediate landing at B (in my case for customs), this is how I proceed: 
-Draw the whole trip in SD on my Android Tablet, by selecting the waypoints and airfields
‌-Select B and C and choose"Land here" in the airfield options
-Then I have two legs on the chart (active one is darker than the other), 2 pilots logs, and 2 flights in the Flight details tab.
- I evaluate how much fuel I have to take onboard, and punch it in, with the first leg active. 
-‌ With the first leg still active, I open the pilot log, and check what fuel there is left at the end of this leg
-‌ Close the pilot log, activate the second leg, open the Flight details tab, and punch in the remaining fuel in the relevant fields.

Does SD offer a short way to do this that I haven't figured out, or does anyone have another way ?

Cheers,
Alexis‌

I would find it useful too if SD automatically carried forward fuel info from the first leg to the second leg. You could of course and a pop warning when the second leg is activated to say "check fuel calculations"....just incase or so that amendments could be made if a fuel uplift was done at the stop off leg.

I fly a simpler Piper than you have so treat each sector as a separate flight. So I have a separate SD log for each flight.
I also do fuel checks manually as I know my engine uses 17.5 litres/hr.
Sometimes one can overcomplicate things with technology!‌‌‌
