Hide/show Jira key in Roadmap, Backlog and Board view

As a project manager I would like to avoid redundant visualisations of roadmap, backlogs and boards when stakeholders ask for overviews and progress of my project. If created thoroughly, I can just jump to my Jira roadmap, and show this on screen in ad hoc meetings. Great. But the key identifier of epics, stories and tasks are disturbing the view for stakeholder. They get confused when seeing it. I would like to be able to toggle it on/off at my convenience, and the setting should be remembered on project level so all users will be affected. Admins could toggle the switch.
