[otrs] Restrict visible ticket types?

Hi, we're using 2.4.7. Is it possible to restrict some ticket types to certain groups or queues, for example with acls? A subgroup of our department has defined a rather extensive set of ticket types that are now confusing the other groups. Also, is it possible to make ticket types mandantory only in some queues? We have some groups that need to set ticket types for reporting while for others they are not used and the currently have to choose a "dummy type", which is invonvenient. Thanks in advance, Karsten
