Does anyone know how to change the display title of Custom Fields in Aurora?

So I've figured out custom fields in Aurora using the new GraphQL API and I have a few test options in our stage instance, but I'm wondering if there's a way to change what displays in the UI. I've read through the dev docs on text key overrides and all the docs on custom fields and I haven't found anything about the display title for these in the UI. I'm guessing it has to do with either a form override or a text key override, but the docs on both are pretty sparse. Wondering if anyone else has figured this out yet. Thanks!

Here's an example of what I'm talking about. We have a custom field on the user entity called "My School" and "myTest" and in the UI it shows "Value of [custom field name]". That's what we'd like to change, if at all possible.
