Sessions should be able to accommodate several consecutive time slots.

Summary

Right now, per session, I can define one (1) time range which is filled with slots.

However, for more complex setups, it would be very useful to define several time ranges.

Reasoning

For example, when running Oral Exams (as we do today), it would be great to have the ability to have 1 session "IDM Oral Exams", and then time slots from Thursday 9:00-12:00, Thursday 14:00-18:00, Friday 9:00-12:00 instead of making 3 (or 2) sessions.
