Review comment:
We've already discussed this in person, but I'm including a comment here
so anyone else can chime in; these kinds of transformation operations are good
candidates for being moved to a separate utility class that supports multiple
types of collection transformations using lambdas and function parameters. This
would allow shorter function calls to improve readability, as well as make it
available to the project. I'd be happy to help out with this effort.
