yes, it is difficult. the number of possibilities is quite large. For the DeZir there are 81,648 possibilities.

For the DeZir there will be 21 unique FU-2 configurations (i.e. engine -2 or engine -1, drivetrain -1). Try to collect all these points following non-overlapping paths.

Along the way in each path you take, collect all the possible upgrades without applying them before the one you intend to apply. For example if you are at 444444 you can collect 6 possible data points - 544444, 454444, 445444, 444544, 444454, 444445 before applying one. in this way you can get a larger data set without having to cloud restore so many times.
