Add location (from Availability) information on calendar next to timeslots

I only use the "List View" layout as I have date overrides. Locations are tied to availabilities. I would like to save customers a click so that when they are browsing available timeslots to book an appointment for, they know which location/availability that is for. Ideally, you have the timeslot - [Availability name]. The variants approach doesn't work well because I want customers to see times across all locations
