In a customization project is there a way to include the data for a custom record or list?

In webstorm, when you import the custom record object there should be a pop asking if you want to include the instances of the custom record. Instances in this case is the data of the custom record

hmm, I don't get that. After I select the record I want to import it confirms it will overwrite existing objects and that's it. Maybe there's a config somewhere I need to update?

Try right clicking the custom record object and select Update With Account object. You should get the pop up

Nice, there it is! Thanks!
