Bush trips persistence over reinstalls

I continue to have issues with Flight Simulator not starting after an automatic update. Probably something wrong with the Microsoft Store. But when I reinstall, I lose all progress on Bush Trips, even though the individual flights do remain in my flight log.

My request is for one or both of the following:

  • Persistence of Bush Trip progress over reinstalls to avoid having to start from the beginning.
  • Ability to start a Bush Trip part-way through (if persistence is not possible)

Thanks!
Paul

The bush trips are stored under Microsoft Flight Simulator > MISSIONS > ACTIVITIES. Perhaps they can be copied before reinstalling?
