I hope I can make clear my question in english 
We have a Confluence space for our Support department. Our teamlead and administrators have all rights for this space and that's ok.
We also use a Whiteboard in that space. When the teamlead is ill or has a day off we want to give a collegue named X the rights to work on the whiteboard. And ONLY the Whiteboard.
Is it possible to give X the rights only for the Whiteboard?
Best regards,
Natascha Hartendorf
