Is it possible to book multiple time slots?

My time base is 30 min, but we need to be flexible when our users book time on our 3d printers. Therefore, I'm trying to make it possible for them to select multiple slots, so they can book 30mins, 1 hour, 1.5 hours, and so on.
I see that the last answer for this question was in 2013, at which point it wasn't possible. I hope we can do this today:slight_smile:
