General :: Including Custom Notes On Orders

I'm looking to simplify some aspects of our company's order database, including standard notes that appear on the sales orders that we send to customers. We have different lines of business and the notes vary. We currently have several reports, depending on the type of order, with the notes hard coded in labels. It's not an elegant, nor scalable, solution.

Our ideal solution: One order report only, with an option for the user to select one or more notes from a list when they enter the order. I'm thinking a popup form with a checkbox next to each note, where each checked note will print on the order report.
