Feature Request: Specifications for different kinds of events

[Aaronnz303]

For non-standart events (like barhopping) it could be helpful to be able to set preferences or something alike

Describe the solution you'd like
Allowing preference fields, e.g. for smoking habits (tolerates smoking, only if necessary, no smoking at all) for participants of said events

Describe alternatives you've considered
A note/option for the group/tutorial to declare which preference setting will be assumed

Is definitely not needed for all kinds of tutorials/groups/..., but the smoking discussion happened in october, so it would be nice to have the possibility to communicate different options to students
