Hey @Luke_Desmond, welcome to the Community!
What I suggest doing in Best Practices Showcase and in general is to not use the item’s name as a Display Column but rather make a separate Display Column where you’d be able to e.g. combine the task’s name with the subtask’s name for easier identification:
Here’s the display column is a combination of project and task, both trimmed to 10 first characters. It’s just one way to do it — you can certainly go more creative about it.
Check out the series btw; they aren’t the most concise but they’ll give you a lot of aha-moments and insights into how to use Coda. The use case there is also very similar to yours.
