Hi
Yes, it's possible. Never thought about it but just tried in a lab server. As seen in the screenshot below.

You have to utilize the customizations you can do in the language pack to do this.
Navigate to Guest\Configuration\Translations\Assistant
Enable TextID's

Each text will now get a number in front of the text, thats the Text ID. Take a note of all menu options you would like to change and keep them for documentation.

Navigate to Configuration\Translations\\Language Packs

Select English, or any other language, and click Translations
Enter the TextID's in the Test ID's box as a comma separated list for the menus you need to change:

Click Refresh, and the textboxes will appear for all the given Text ID's. Enter your custom text and Save.
Disable the Text ID option enabled earlier.
If your users have other supported languages than english as default language in thier web browsers you have to do the same for the other languages as well. Or block automatic language selection and only have English.
These changes will apply for all users regardless of the operator profile they are logged in with.
