Make single-position roles un-favorite-able

[Sundance]

what if I want it to randomly choose between only rd, botanist, and barman?

It's not that big a stretch to have the wildcard option to be customized to pick from a pool of jobs, rather than every job.

An example how it would work with yours would be the following:
You select the aforementioned jobs in the wildcard pool.
You roll barman. Sundance has already selected barman as his favorite and is the only person who has it as his favorite, so your odds are 50:50. You lose the odds.
You roll again, discounting barman. You get botanist. Nobody had botanist as favorite so you get the job.

Wildcard would mean that people who have their job in their favorite slot are not guaranteed to get it if they're the only person who has it on favorite and there's someone with a wildcard option and they roll that job.

Obviously the rule for wildcard would mean that you can't have just 1 job in wildcard (otherwise there'd be no roll)
