Multiple dates event (not recurring)

Hello,

how do I create a multiple dates event whose dates are not recurring ?
e.g a training that takes part from 9am to 5pm on August 3, 7 and 22.
(A more refined approach would be August 3 9am-5pm, August 7 9am-5pm, August 22 9am-12am … maybe I am asking too much?)

I am not happy creating multiple events, because people can only book the event starting on August 3 including the 7 and 22, and with one event per date this is not clear.

Thanks for any tip/trick !
