Lead Inbox - Can you mark a lead as "Unread" or change the flag per user?

We have about 8 people using the lead inbox and people can pick what leads they want to pursue. If anyone clicks on a lead it unbolds the lead (marks it as read) for everyone. Is there a way to have this change so the "read" flag is on a per user basis vs organization wide? We need a quick way for each person to know if they have seen the lead. Since the leads are unbolded when anyone looks at them there's no way for each person to review only the ones they have not seen.
