CONCRETE MIX REPORTING

We are using 2 seperate concrete mixes on our CI project. A letter from the manufacture details the raw materials and ratios for each mix. Each type of mix is clearly identified on the invoice. We are using the concrete submittal form found in the toolkit.Can we sum all of the concrete by each mix type and then average based on the munufactures letter? Or must we input each indvidual delivery and provide each individual batch mix on a separate line?(possibly 100 line items)Thanks for any suggestions.
