You have two options to populate estimates for newly added facilities as a returning user.
You can restart measurement and complete a new estimate for all your active facilities. Not that this option requires that you generate a new workbook and will delete your existing work. Please be sure to save a copy of your existing workbook before restarting measurement to complete a new estimate.
Or, if possible, you can extrapolate data from a similar supplier and scale that to the new facilities based on % production instead to serve as proxy data.
