The short answer is no. If anything, BeerSmith will adjust the OG and est. APV with the different efficiency. In looking through the program, it appears that the only way to adjust the efficiency would be to change the Brewhouse efficiency in your equipment set up for the different sparge options. I would only change it based upon the results you get from brewing a batch and taking careful measurements of the sg and volumes through the process. You could then set up an equipment profile specifically for batch sparging versus fly or no sparge processes.
