Improvement for error page displayed when user is not part of a group

[kiratskitizing]

I would like to request for improvement of the page being displayed, if a user who is not a member of a group attempts to visit an ouwiki activity (settings: Sub-wikis = One wiki per group, Common module settings: groups = separate groups)

This is the current page being displayed,

If possible, could a page similar to an assignment module be displayed?
