List of CAPACITY INFORMATION per slot service visible

It's very difficult to know the exact total of people per service. I have installed the addon Multiple Quantity module, one person can book several spots, but on the calendar I only see one name.

I limit the maximun number of people per session, but then I have no easy way to know how many are going to the event.

As on my case I am working with motorbike trainings, I need to know how many people will show, as I need to prepare the same number of bikes, and it's very hard for me now to prepare for the trainings.

I really need this feature you guys have all the info there..
you already have the value there on CAPACITY INFORMATION, can you make it visible somewhere, or some report or anywhere..

something like this table...

The fact that I dont have this will causing a lot of lost time to understand how many people I am having per training... help me here...

Really appreciate it..
