"Your Network sub intro post text" field different text per page?

Currently the blogs.mu theme is showing the "Your Network sub intro post text" on all pages. As I do believe is very nice and helpful at the home page, it does not add any value to the other pages (blogs,groups, etc)

It would be really nice if this text could be adjustable per page? So the subintro post text for lets say "groups" page to have some related info about groups and not to be the same text as in the homepage.

If this is much effort to realize I would like to have it only at the homepage as it makes more sense.
