Allow boolean operators on reg rules

It would be useful to have AND/OR/NOT options when creating a reg rule and when filtering by categories. At the moment if you select a Job Title and a Department it only registers someone with both categories.

If you want to register everyone with a Job Title as well as everyone in a Department, you'd have to create two separate rules. With operators you could select Job Title OR Department.

Using NOT would be useful to exclude people e.g. specific Job Titles from a Department
