Dynamic group access

Dynamic groups are similar to the Assignee Group (field ID 112), except that they are defined by the developer and include field and group IDs in the range of 60000 to 60999. For example, when you create a group with group ID 60000, its user list includes the individual user name or the members of any group or role that appears in field ID 60000.
