Forced flowmeterlevel at every single keg of Grolsch Premium Pilsner

[Jottee]

When using multiple kegs which aren't full you can make a Grolsch Premium Pilsner entry, however for every single keg you need to fill in the flowmeterlevel. It would be more useful if you would have to fill in 1 start-level and 1 end-level instead of all the irrelevant levels inbetween opened kegs.
