As a user, it can be confusing if I have multiple mock-ups on a field with only a date as the title. I end up clicking into the wrong one many times. I'd like to be able to Name my mock-up files.
Thanks for submitting this idea. It is currently possible to rename mockups. You can do this by selecting the mockup on your record and then clicking its name in the preview. Please reach out to us at firstname.lastname@example.org if you have any trouble with this.
