If you uncheck the reset view on refresh then the model should not refresh while you enter data. But in the event that it does, this will not slow down the input. You can switch spreadsheets, enter data, and continue to new spreadsheets simultaneously while the view refreshes. I know this is not what you want, but it shouldn't be a speed issue.
