While we're on the subject of Text Blocks, I'm adding something to my product (Rentals for Adagio) that could be implemented in other Adagio products. Add an option next to the 4 lines of text for each item. The option is 'Insert comments on contract'. In your case, it could be a sales or purchase order. When checked, the 4 lines are automatically as comments (or instructions), after the item. This is in addition to Text Blocks.
