Can I have hours tab opened on the next day available by default ?

All is in the title I guess...
I'ld like to avoid one click to the visitor by letting the next day available open so that he just have to pick up an hour to go ahead !
I guess it could be an awesome update for everyone by the way! but do you know how I could trick this to happen ?
I've seen that hours get the class "hidden" but I don't see a click action or a way to access them...
I'm very peased by the customization I've made on Appointment+ though, have a look:

Thank you in advance for your awesome support ! I love WPMU guys! :smiley:
