I use ExpressGenerator to create strategies with some basic Acceptance Criteria and Monte Carlo. I then import into EA Studio using Validator. I do not use any acceptance criteria or Monte Carlo or other filtering during the validator process. I then go to the Collections to do my final filtering. I do my final filtering here instead of in ExpressGenerator. If I were to do all my filtering in ExpressGenerator I would not be able to make filtering changes to collected strategies. By doing my final filtering in EA Studio Collections I can change filtering to select the EA I want to use.
