Contribution notes from all eligible contributions, single-row output

Hi all. This is a long shot, but I'd love to have one output element for contribution notes, that I can filter by campaign as usual, that will not output multiple rows, but that will concatenate all valid contribution notes into one column output. Does anyone know if this is even possible?

The use case is to pull info for the program book. The output set will return one row for each constituent (perfect!) until I add contribution notes to the output set. This creates tons of extra work for our sole development associate.
