I'm in the situation where I've been given different roles. Currently, this means that Redmine grants me all the privileges that come with the different roles I have.

I would like to be able to select one role from the list of roles I'm allowed to take. This way, when I'm wearing my @Developer@'s hat, I'm only granted the privileges associated with a @Developer@. But when I'm wearing my @Change Control Board@ hat, I'm given more privileges (e.g. change the status of an issue to @OnHold@, which a developer is not allowed to do).
