How to increase number of contacts shown in CRM Campaign ?

Hello Everybody,
I can't find a way of increase the number of contacts displayed per campaign.
It is limited to 10 contacts which is very distressing when I need to update the status of several contacts. What a huge waste of time and energy
Is there a way to show 100 or more contacts at the time or better to do mass editing ?

Thanks in advance for your help
Didier
