Scheduling appointment category heading fonts size and uppercase

Hi,

I'm trying to edit the font size and case (to uppercase) and colour of the category titles on the appointments page in scheduling.

Please see link  below.

The category titles are "Men's Services" and "Women's Services". Ideally I would like these to stand out more.

Thanks in advance for any help I can get.
