Additional columns on the main Collaborator web user homepage

Hi,

just wondered if it's possible to have additional columns to the main user web page for Collaborator.

At the moment there are Review, Progress, Author, My Role, and Deadline.



Some users are in a fair number of groups, for instance, and would like the ability to sort their main views accordingly.



And if there is a way, will it have to be system wide, or can it be user specific?



thanks
