Import the planePerformance.xlsx in Aircraft Editor

I’m following the How to Create an Aircraft section of the SDK and that is a
WONDERFUL piece of documentation and hope the following sections will be
completed soon! In the first steps it is suggested to fill in the
PlanePerfomance.xlsx to obtain useful values to input in the Aircraft Editor
Would it be possible to import it directly in some way, maybe in some of the
wizard steps?
