Check boxes... a lot of them

[Alex.1 6]

Hi everyone

I've got this: 

Each day is created using a checkbox field... and as you can see there are a lot of them.  Upon listing submission the user has to perform a lot of clicks which I would like to avoid by adding a "check / uncheck all" button(s). 

Any help would be welcomed. 

Thanks, 

Alex
