ModelBuilder reruns the entire model if I
1. Open a model and try to run a step, even if the previous steps show they have been run
a. Example: The previous step reprojected dispersed points layer into a feature class and I tried to run the append into an empty feature class step. I don't want to rerun the entire model because dispersing symbols takes 35-45 minutes. Plus the dispersed symbols are already saved in the reprojected feature class.
2. When I make a minor change to a step (changing a geoprocessing tool parameters), it reruns the whole model even though the model has already run up to that point.
