Hey there Bill! :)
Eli here from Shopify; this is definitely a feature that makes sense to me, and one that I can see being useful for merchants with a multitude of files. Currently, this is something that hasn't yet been built into the backend admin, but which I have notified our developers of per your question here. Furthermore, I have left your store name / e-mail attached to the request for this feature, such that, when it comes to fruition, you will be notified personally!
All the best, and don't hesitate to fire any other questions my way.
